Answer:A

Explanation:

Answer:

Why does ecological succession occur? Every species has a set of environmental conditions under which it will grow and reproduce most optimally. Ecological succession may also occur when the conditions of an environment suddenly and drastically change.

Hemophilia is a genetic disorder caused by a mutation in the X chromosome. Females have two X chromosomes, while males have one X and one Y chromosome.

Females who carry a mutated X chromosome have a 50% chance of passing it on to their offspring. Males who inherit the mutated X chromosome from their mother will have hemophilia, while females who inherit the mutated X chromosome will be carriers of the disorder.

In the case of the Romanov family, it is possible that the female members who carried the mutated X chromosome did not pass it on to their offspring. It is also possible that some of the male members who inherited the mutated X chromosome died before having children, or their children died before being diagnosed with hemophilia. Additionally, it is possible that some of the members of the family were misdiagnosed, or that there were other genetic factors that influenced whether or not someone developed hemophilia.

Answer:

f. 1- Hb; 2- dissolved in plasma

Explanation:

Transport of oxygen in the body occurs in two way; oxygen bound to hemoglobin and oxygen dissolved in plasma.

1. Bound to hemoglobin :

Hemoglobin, or Hb, is a protein molecule found in red blood cells and is responsible for the colour of red blood cells. It is composed of four subunits of two types of the protein globin: two alpha subunits and two beta subunits. Each subunit surrounds a central heme group (red in color) that can bind one oxygen molecule.Therefore, each hemoglobin molecule can bind and transport four oxygen molecules. About 98.5% of oxygen is transported in the body bound to hemoglobin.

2. Oxygen is only fairly soluble in blood plasma. As a result, only 1.5 percent of oxygen in the blood is dissolved and transported in blood plasma.

Answer:

The correct statement would be:

A] The body cell has 52; the sex cell has 26.

Explanation:

In sexually reproducing organisms, body cells, also known as somatic cells, typically contain a diploid number of chromosomes, which means they have two sets of chromosomes. In the case of a snapping turtle with 52 chromosomes, its body cells will have 52 chromosomes.

On the other hand, sex cells, also known as gametes, are involved in reproduction and are responsible for transmitting genetic information to the next generation. Gametes have half the number of chromosomes found in body cells. This reduction in chromosome number is achieved through a process called meiosis. Therefore, the sex cells of a snapping turtle would have 26 chromosomes, which is half of the number of chromosomes present in its body cells.

Answer:The protein is most likely composed of multiple polypeptide chains that are held together by disulfide bonds

Explanation:

The Disulfide bonds in protein membranes are usually seen in bacteria and eukaryotes.

Answer:

Option B

Explanation:

Since the usual shape of the protein is supposed to be globular and even after treatment, it still produces the same globular proteins despite the reduction of its disulphide bonds.

The disulphide bonds should have disrupted the shape formation if it had been a mechanism for its shape formation but since multiple globular polypeptide resulted from the treatment it can be assumed that the multiple polypeptide chains are held together by disulfide bonds which are hydrolyzed by the chemical.

The acceleration of the car is 2 m/s².

The average velocity of the car is 2 m/s.

The equation acceleration = (final velocity - beginning velocity) / time can be used.

Given:

Initial velocity (u) = 0 m/s (since the car starts from rest)

Final velocity (v) = 20 m/s

Time (t) = 10 s

Using the formula, we can substitute the values:

acceleration = (20 m/s - 0 m/s) / 10 s

acceleration = 20 m/s / 10 s

acceleration = 2 m/s²

Therefore, the acceleration of the car is 2 m/s².

You can use the following equation to determine the average velocity: average velocity = total displacement / total time.

The initial position and the final position are identical since the automobile begins at rest. As a result, the displacement and the ultimate position are equal.

Given:

Displacement = 20 m

Time (t) = 10 s

Using the formula, we can substitute the values:

average velocity = 20 m / 10 s

average velocity = 2 m/s

Therefore, the average velocity of the car is 2 m/s.

Explanation:

-6 ≤ y < ∞

Explanation: a molecule has 2 or more atoms bonded chemically by various methods like ion and covalency

The first benefit is that natural gas emits from 50% to 60% less carbon dioxide than coal, reducing the contributions to climate change and respiratory diseases.

The second benefit is that it is a more reliable source, as it is abundant, more easily transported and stored. All of this reduces the risk of accidents that could cause leaks and unforeseen pollutions, and it also reduces the costs (the money can always be used to enhance eco-friendly processes instead of processes that are more harmful for the environment).

There is a supply of undeveloped eggs in the ovaries. At the beginning of the menstrual cycle, between 6 and 12 undeveloped eggs in the ovaries start to mature. A layer of cells grows around them. At around day 5 of the menstrual cycle, the biggest follicle will continue to grow for another week. At around day 14, the follicle breaks apart, and the wall of the ovary ruptures. The egg is released from the ovary into the fallopian tube, where it can get fertilized. This process is called ovulation. The uterus also changes during the course of the menstrual cycle. It has a lining of cells on the inside, kind of like a cushion with a lot of blood vessels. Fallopian tubes connect the ovaries and the uterus. The uterine cycle begins with menstruation. This is the process through which most of the lining and blood from the last uterine cycle are cleared out of the uterus to prepare for a new attempt at pregnancy. Starting at around day 5, the lining starts to grow. It builds back up to prepare a place for the egg to grow if it gets fertilized. After ovulation, the egg reaches the oviduct. If sperm cells have entered the vagina during intercourse, fertilization may occur at any time in the next two weeks. Then the fertilized egg will move into the uterus and implant itself into the lining, where development will begin.

The events in the menstrual cycle are primarily triggered by hormonal signals from the body. The menstrual cycle is a complex process regulated by the interplay of hormones produced by the hypothalamus, pituitary gland, and ovaries.

1. Hypothalamus: The hypothalamus, a region of the brain, releases gonadotropin-releasing hormone (GnRH) in a pulsatile manner. GnRH stimulates the pituitary gland.

2. Pituitary gland: In response to GnRH, the pituitary gland secretes two important hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

3. Follicular phase: At the beginning of the menstrual cycle, FSH stimulates the growth and maturation of ovarian follicles, which contain the developing eggs (oocytes).

As the follicles grow, they produce estrogen, a hormone that helps prepare the uterus for a possible pregnancy.

4. Ovulation: As the estrogen levels rise, it triggers a surge in LH production by the pituitary gland. The LH surge leads to the release of a mature egg from the ovary, a process called ovulation.

5. Luteal phase: After ovulation, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. The corpus luteum produces progesterone, which prepares the uterus for potential implantation of a fertilized egg.

6. Menstruation: If pregnancy does not occur, the levels of estrogen and progesterone decline. This drop in hormone levels triggers the shedding of the uterine lining, resulting in menstrual bleeding.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Here are some uses of biotechnology in the production of washing powders:

Enzymes: Enzymes are commonly used in washing powders to enhance the cleaning efficiency and remove various types of stains.  Proteases, amylases, lipases, and cellulases are examples of enzymes used in washing powders. These enzymes break down protein-based, starch-based, lipid-based, and cellulose-based stains, respectively, into smaller fragments, making them easier to remove during the washing process.

Bio-surfactants: Surfactants are essential components of washing powders as they help to remove dirt and oil from fabrics. Biotechnology allows for the development of bio-surfactants, which are surfactants derived from biological sources, such as bacteria or yeast. These bio-surfactants are more environmentally friendly than traditional surfactants as they are biodegradable and have lower ecological impact.

Microbial Strains: Biotechnology can be used to isolate, characterize, and optimize microbial strains that produce enzymes or bio-surfactants. Microorganisms, such as bacteria and fungi, can be engineered or selected for their ability to produce specific compounds that enhance the cleaning performance of washing powders.

Genetic Modification: Genetic modification techniques can be employed to enhance the properties of microorganisms used in the production of enzymes or bio-surfactants. This allows for the creation of microorganisms with improved characteristics, such as increased enzyme activity or enhanced stability under varying conditions.

Fermentation Processes: Biotechnology facilitates the use of fermentation processes to produce enzymes and bio-surfactants at a large scale. Fermentation involves the controlled growth of microorganisms in bioreactors, where they produce enzymes or bio-surfactants through metabolic processes. This enables the efficient and cost-effective production of these ingredients for use in washing powders.

One way that deposition by gravity slowly changes Earth’s surface is by creating talus slopes. Talus slopes are piles of rock fragments that accumulate at the base of cliffs when rocks break away from the cliff face and fall, bounce or roll downslope. Talus slopes are common in areas that experience freeze-thaw weathering, which causes chunks of rock to lose contact with the cliff face and fall. Talus slopes can affect the shape and stability of the landforms they cover, as well as the vegetation and wildlife that live on them.
