Answer:

Bacteriorhodopsin

Explanation:

Purple Halobacterium species owe their color to bacteriorhodopsin, a light-sensitive protein.

The species will most likely survive if the prey population in the area decreases (A). Species X because it is difficult to bring down a small prey is correct option.

If the prey population declines, species X, which has short canine teeth and is specialized for small prey, would benefit. This is so because of how tough it is for them to take down a large prey due to their physical makeup. In contrast, due to their specialised traits, Species Y, with 1-foot-long canine teeth and an adaptation for huge food, may encounter difficulties when hunting smaller species. Therefore, in a scenario where the population of the prey drops, Species X has a higher chance of surviving.

Therefore the correct option is (A).

Interconnected

Explanation:

The word that best describes the feeding relationships in a food web is "interconnected."

A food web is a complex network of interrelated food chains that shows the flow of energy and nutrients through an ecosystem. The organisms in a food web are connected to each other through predator-prey relationships, where some organisms are consumers and others are producers.

Each organism in the food web depends on other organisms for food, and their survival is interconnected with the survival of other organisms in the ecosystem. Therefore, the feeding relationships in a food web are highly interconnected.

The feeding relationships in a food web are highly interconnected, with each organism depending on others for survival. A food web is a dynamic system, and changes in one part of the web can have far-reaching effects on the rest of the ecosystem.

Based on the symptoms described, Bob's diagnosis could be kidney stones or renal calculi.

Kidney stones are hard deposits that form in the kidneys and can cause severe pain when they move through the urinary tract. The excruciating pain originating from the left posterior flank and radiating downward is a characteristic symptom of kidney stones.

The presence of blood in the urine, a condition known as hematuria, is also common with kidney stones due to irritation and injury to the urinary tract.

Bob's difficulty in standing up straight or walking can be attributed to the intense pain caused by the movement of the kidney stone, which can make it challenging to find a comfortable position. The pain often comes in waves and can be described as one of the most severe pains experienced.

To confirm the diagnosis, Bob should seek medical attention for a thorough examination.

The doctor may perform imaging tests, such as a CT scan or an ultrasound, to visualize the kidney stone and determine its size and location.

Treatment options may include pain management, medication to facilitate the passage of the stone, or, in more severe cases, surgical intervention to remove the stone.

Answer:

The scientists credited with formulating the postulates of the cell theory are Matthias Schleiden, Theodor Schwann and Rudolf Virchow.

Explanation:

Cell Theory contributed to the understanding of how living organisms are made up of cells, as well as the role that cells play in life related functions.

The experiences of Schleiden, Schwann and Virchow laid the foundations of cell biology, whose main conclusions are summarized in the three postulates of Cell theory:

Matthias Schleiden, when observing plant tissue under a microscope, was able to prove that this tissue was made up of cells, and that all plants possessed them. In 1837 he would postulate that the cell is the fundamental unit of life and that all plants were made up of cells.

A similar experience to that of Schleiden, but with animal tissue, was carried out in 1838 by the German physiologist Theodor Schwann, where he could conclude that in animal tissue there were also cells. This gave way to the second postulate that all living organisms are made up of cells.

In 1863, while studying cancer, the anatomist Rudolf Virchow observed how cells were able to reproduce themselves and give rise to new cells. The third postulate of the theory is due to this scientist, who was able to conclude that every living cell originates from another cell.

Answer: D. A bacterial plasmid with a target gene inside it best describes Recombinant DNA.

Explanation: Recombinant DNA is formed by inserting a target gene of interest into a plasmid, which is a circular piece of DNA that can replicate independently in a bacterial cell. This results in a bacterial plasmid with the target gene inside it. The recombinant DNA can then be used for various purposes such as producing proteins, testing gene function, and more.

The distribution of invertebrates among different colors suggests that the type of predator targeting them might have color preference or selectivity.

The fact that there are significantly more blue invertebrates (30) compared to black (25), brown (25), yellow (6), and orange (4) indicates that the predator might have a preference for blue-colored prey. This preference is evidenced by the higher number of blue invertebrates captured compared to other colors.

Additionally, the predator seems to show a relatively equal preference for black and brown invertebrates since their numbers are the same. However, it is important to note that the sample size of the invertebrates may affect the observed distribution, and further investigation would be required to draw definitive conclusions.

Understanding the predator's color preference can provide insights into its visual perception and hunting strategies. It could indicate that the predator has developed adaptations to target specific color morphs or that certain colors are more conspicuous or attractive to the predator's visual system.

The relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.

Barnacles are a type of sessile organism, which means they are unable to move freely from one location to another. In order to survive, they need to attach themselves to a solid surface, such as a rock or the skin of a whale. When barnacles attach themselves to the skin of a whale, they create a home site where they can filter-feed and reproduce.

While the barnacles benefit from this relationship by gaining a home site, there is no evidence to suggest that the whales benefit or are harmed by having barnacles attached to their skin. Barnacles do not consume or harm the whale's skin or tissues, and there is no evidence to suggest that the presence of barnacles has any impact on the whale's health or behavior.

Therefore, the relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.

dairy

Explanation:

Animal-based foods (meat, poultry, fish, eggs, and dairy foods) tend to be good sources of complete protein.

Lactic acid fermentation is the process in which 6 carbon sugars, such as glucose, are used to generate cellular energy, the waste product of this process is the metabolite lactate, which is the lactic acid in solution.

Fermentation is an anaerobic pathway to break down glucose.

The first step of this process is glycolysis, through this process the glucose molecule is converted into two molecules of pyruvate, and the energy stored in the molecule's bonds is released.

The second step of the process is the restoration of the NAD+ molecules. During this process, NADH transfers its protons to pyruvate and is oxidized to form NAD+.

This process occurs in the muscle cells when the tissue needs energy and there is not enough oxygen available, for example, during a very intense exercise.

The waste product of this process, the lactate, is carried away by the bloodstream to the liver, where lactic acid is used to synthesize glucose. (This metabolic process is called Cori's cycle) When the lactate is not removed from the muscle fast enough, it causes the pH to decrease, which causes the muscular tissue to not work correctly. This may cause soreness and muscle cramps.

There are bacteria that produce lactic fermentation, these bacteria are called Lactobacillus and are commonly known as "yogurt bacteria" it uses milk as a source of substrate for the fermentation process, and thus yogurt is produced.

The only option that is not associated with Lactic Acid Fermentation is "bread"

Based on the results of the experiment it can infer that its temperature has an impact on the highest health rating. Because it requires low temperatures, it would be simple.

It was giving in the hypothesis that Anglerfish in different lighting conditions will have different health rating. The anglerfish will have a (worse) health rating if the light level or the temperature level in the habitat is raised.

Compared to narwhal at low and high temperatures The narwhal's health grade will be (lesser) if the habitat temperature is raised.

Anglerfish under high and low pressure conditions The anglerfish will have a (higher) health grade if the habitat's pressure is increased.

So, according to the experiment's findings, the highest health rating is influenced by the temperature. It would be easy because low temperatures are needed.

Steps of Double Fertilization.

1. Germination of pollen on stigma :

(i) By absorbing secretion of stigma pollen swells up and outer layer exine ruptures whereas inner lintine comes out in the form of pollen tube.

(ii) Branched polen tube is formed in amentiferae group.

(iii) In families malvaceae, cucurbitaceae, etc. polysiphonous condition (many pollen tubes from a single pollen) is found.

2. Path taken up by pollen tube :

(i) Pollen tube pierces through stigmatic papilla into the tissue of style.

(ii) Filiform apparatus of synergids secrete some chemotropically active substances, which promotes porogamy.

(iii) Obturator (special structure) act as a bridge for growth of pollen tube.

(iv) Cations are naturally occurring chemotropic agents in the pistil.

3. Entry of pollen tube into embryo sac :

(i) It enters into the ovule by either of the two methods; porogamy, chalazogamy or mesogamy.

(ii) Irrespective of the mode of entry of pollen tube into the ovule, the pollen tube always enters into embryo sac at micropylar end (Porogany).

(iii) If enters through chalaza (base) it is termed chalazogany.

(iv) If pierces through integuments, it is called mesogamy.

(v) Tip of pollen tube penetrates embryo sac and reaches egg apparatus.

4. Syngamy (Generative fertilization)

(i) Pollen tube burst as tube nucleus disorganises.

(ii) One of male gametes fuses with egg cell or oosphere.

(iii) Deploid oospore or zygote is formed.

5. Triple fusion (Vegetative fertilization) :

The other gamete fuses with secondary nucleus forming triploid primary endosperm (PEN) which later give rise to endosperm.

Answer:

Double fertilization is a process unique to flowering plants (angiosperms) in which two sperm cells fertilize two different structures within the female reproductive system. The steps of double fertilization are:

Double fertilization leads to the formation of both the embryo and endosperm within the ovule, which ultimately results in the development of a seed.
