Answer:

Behavior, biological features, color, form, and size are a few examples of visible traits.

Explanation:

All of an organism's observable traits, or phenotype, are the outcome of the interplay between its genotype (total genetic inheritance) and environment.

Answer:

Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Explanation:

The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.

Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

Answer and Explanation:

The brain is composed of three main structures, the cerebrum, cerebellum, and brain stem. The brain sends chemical and electrical signals throughout the body to regulate different biological functions and sense environmental changes. The brain communicates with the majority of the body through the spinal cord.

Explanation:

For the Punnett square, for each genotype (Letters), you just find out how many of a certain combination in the boxes that there are .

(e.g, if there's one BBRR = 1/16, if there's 3 BbRrs = 3/16)

Do that for each Genotypic Ratio.

For the phenotypic ratio, you need to find out which genotype is dominant, and if the genotype combo will show up in a guinea pig physically.

For example, for the Black, Rough Phenotype, it would be the BBRR combo, since both are dominant and will be present in the guinea pig.

A dihybrid cross is a breeding experiment that involves studying the inheritance patterns of two different traits simultaneously.

It examines the inheritance of two different genes located on different pairs of homologous chromosomes. This type of cross allows for the analysis of independent assortment and the determination of the phenotypic and genotypic ratios of offspring.

The genotypic and phenotypic ratios are:

Genotype ratio:

BBRR: 1/16

BBRr: 2/16

BBrr: 1/16

BbRR: 2/16

BbRr: 4/16

Bbrr: 2/16

bbRR: 1/16

bbRr: 2/16

bbrr: 1/16

Phenotype ratio:

Black, rough: 9/16

Black, smooth: 3/16

White, rough: 3/16

White, smooth: 1/16

Muscular disorders can affect both men and women. However, certain disorders may have a higher prevalence in one gender over the other.

For example, Duchenne muscular dystrophy, a genetic disorder that primarily affects muscle strength and function, is more commonly seen in boys than girls.

On the other hand, fibromyalgia, a chronic pain disorder, is more common in women than men. Other muscular disorders, such as myasthenia gravis, can affect both men and women equally.

It is important to note that regardless of gender, early detection and management of muscular disorders can help improve overall quality of life and prevent further progression of the disorder.

Seeking medical attention and discussing any concerns with a healthcare provider can help in identifying and managing any muscular disorder.

You need to take 0.02 L of the stock solution and make up to the one liter mark.

The term serial dilution has to do with the ability to prepare a solution from another. We have to determine the amount of the 2M solution to use.

1)  Thus, you would need to add 90 mL of distilled water to the 10 ml of a 2M solution to obtain the 100 ml of a 10 mM solution.

2) Using C1V1 = C2V2

C1 = Initial concentration

V1 = initial volume

C2 = final concentration

V2 = final volume

50 * v1 = 1 * 1

V 1 = 1/50 = 0.02 L

Answer:

In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).

Biologists introduced the Texas puma into Florida to address the declining population of native panthers.

The Texas puma, also known as the Florida panther's closest relative, was introduced to increase genetic diversity and strengthen the population's resilience.

By introducing new individuals into the Florida panther population, biologists aimed to reduce the risks associated with inbreeding and enhance the long-term survival prospects of the species.

This effort sought to restore balance to the ecosystem and ensure the preservation of this iconic and endangered big cat species.

Answer:

B. similar to the cells just treated with the dye - 0% dead

Explanation:

According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.

Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.

A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

Answer:

The vertebral column, or backbone, is made up of a series of repeating, or metameric, structures called vertebrae (singular, vertebra) that extend from the head to the tail along the dorsal (top) side of the body. The function of the vertebral column is to provide the central support structure of the endoskeleton, allowing an organism to hold its shape. It also serves to house and protect the spinal cord that that lies within the column.

The structure that develops in the mesoderm and allows for more complex internal organ formation is coelom.

"The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".

Explanation:

The food we eat undoubtedly contains energy. This energy is stored in the bonds of the molecules that make up the food. However, the food undergoes the process of digestion to yield glucose (a sugar). This glucose sugar is used in the process of CELLULAR RESPIRATION to synthesize a form of chemical energy usable by cells called ATP.

ATP or Adenosine triphosphate is a molecule that stores chemical energy in living cells. It is the molecule that directly powers all of our cellular activities. Hence, the statement in this question is FALSE. The correct statement should be "The energy contained in the food we eat is used to synthesize the energy that directly powers all of our cellular activities".

Osmosis affects plants and animal cells differently because plant cells have a cell wall, so they become turgid, or swollen, instead of bursting. The correct option is B.

Osmosis is the diffusion of particles from a low concentration region to a high concentration region. It is the movement of solvent particles through a semi-permeable membrane.

Animal cells do not have a cell wall, and plant cells contain a cell wall. Plant cells contain a vacuole and animal cells do not. These are the difference between these cells.

The process of osmosis act differently on plant cell and animal cell. The animal's cell will burst quickly in a concentration, and the plant cell will not burst out because it contains a cell wall.

Thus, the correct option is B. Plant cells have a cell wall, so they become turgid, or swollen, instead of bursting.

Large bodies of water like the Atlantic Ocean and the Gulf of Mexico, as well as the dominant winds, help to keep Florida's coast from getting too hot.

The water bodies can absorb and hold a lot of heat without rapidly altering temperature because of their high heat capacity. As a result, throughout the day, the coastal waters serve as a heat sink, soaking up heat from the nearby land and air.

In general, vast bodies of water, prevailing winds, and ocean currents work together to regulate the temperature along Florida's coast, resulting in a more consistent and mild climate than parched desert biomes.
