Plants are able to produce energy from sunlight through photosynthesis. How do the products of photosynthesis in plants benefit animals, who cannot produce energy from sunlight?
Answers
Answer:
They produce sugars in order to survive and grow. Animals eat plants and take advantage of the nutrients produced by the plants. They also breathe in the oxygen produced as a by-product of photosynthesis
Explanation:
Plants use the energy in sunlight, water, and carbon dioxide to produce sugars which are used to provide chemical energy to power cellular processes. These sugars are also stored as starches.
Animals cannot produce their own food, and instead, rely on plants and other animals as a food source to power their own processes. Animals eat plants and obtain the food that plants have produced by photosynthesis. This is mostly carbohydrates (sugars and starch) but also some fats, proteins, and vitamins.

Which of the following occurs in vascular land plants but not charophytes (stoneworts)?
A) sporopollenin
B) lignin
C) chlorophyll a
D) cellulose
E) chlorophyll b
Answers
Lignin occurs in vascular land plants but not charophytes because lignin is a complex polymer found in the cell walls of vascular land plants, providing structural support and rigidity.
The correct answer is option B)
Lignin is a complex polymer found in the cell walls of vascular land plants, providing structural support and rigidity. It is responsible for the ability of vascular plants to grow tall and develop sturdy tissues, such as xylem and phloem, which are essential for water and nutrient transport throughout the plant.
Charophytes, or stoneworts, are a group of green algae that are considered the closest living relatives of land plants. While they share many features with land plants, they lack true vascular tissues and do not possess lignin in their cell walls. Without lignin, charophytes do not have the same level of structural support as vascular land plants, and they typically have a more limited growth form.
The other options listed (A) sporopollenin, (C) chlorophyll a, (D) cellulose, and (E) chlorophyll b are found in both vascular land plants and charophytes. Sporopollenin is a durable polymer that forms the outer layer of spores and pollen grains, which is present in both groups. Chlorophyll a and chlorophyll b are photosynthetic pigments found in the chloroplasts of both charophytes and vascular land plants. Cellulose, a polysaccharide, is a major component of the cell walls in both groups as well.
In summary, the presence of lignin is a characteristic that distinguishes vascular land plants from charophytes. Vascular land plants possess lignin, which provides structural support and allows for the development of specialized tissues, while charophytes lack this feature.

How do you get genotypic ration off of genotype outcomes
Answers
To determine the genotypic ratio from genotype outcomes, you need to count the number of individuals with each genotype and express the results as a ratio.
The genotypic ratio represents the relative proportions of different genotypes within a population.
For example, let's consider a cross between two individuals with the genotype Bb. The possible genotypic outcomes of their offspring could be BB, Bb, and bb. Suppose you have performed the cross and obtained the following genotype frequencies: 10 BB, 20 Bb, and 15 bb.
To calculate the genotypic ratio, you divide the number of individuals with each genotype by the total number of individuals and express the results as a ratio. In this case, the genotypic ratio would be:
BB: 10/45 = 2/9
Bb: 20/45 = 4/9
bb: 15/45 = 1/3
So, the genotypic ratio would be 2/9:4/9:1/3, which simplifies to 2:4:3.
By determining the genotypic ratio, you can understand the distribution of genotypes within a population and gain insights into the inheritance patterns and genetic diversity.

A change in the allele frequency of a particular species or a population over time is known as genetic drift.
Genetic drift, which is also sometimes known as the allelic drift or the Wright effect, is basically the change in the frequency of an already existing gene variant present in the population due to a random chance. Genetic drift may end up causing the gene variants to disappear completely and thereby reduce the genetic variation in a population.

Answers
Answer:
The cell becomes haploid, with 23 single chromosomes.
Explanation:
Hope This Helps.
The process of meiosis, a form of cell division that decreases the number of chromosomes in the cell from two sets to one set, occurs as the egg matures.
The creation of gametes, which are reproductive cells with just one pair of chromosomes, depends on this process. The main oocyte, which has two sets of chromosomes, is formed at the start of meiosis. The two sets of chromosomes align into homologous pairs during meiosis I, cross across, and combine to create new genetic combinations.
Four daughter cells are created as a result of this process, and each one of them has a set of chromosomes made up of the original two sets. The four meiosis II genes are dividing to become double.

At the end of aerobic cellular respiration, how many total carbon dioxide molecules are produced for each glucose metabolized?2463236
Answers
At the end of aerobic cellular respiration, a total of 6 carbon dioxide (CO2) molecules are produced for each glucose molecule metabolized.
During the process of aerobic cellular respiration, glucose is broken down into pyruvate molecules through glycolysis. Pyruvate then enters the mitochondria and undergoes the citric acid cycle (also known as the Krebs cycle), where it is further broken down to produce energy. During this process, CO2 is released as a byproduct of the reactions.
In the citric acid cycle, each pyruvate molecule is broken down into 3 CO2 molecules. Since each glucose molecule is metabolized into two pyruvate molecules, the total number of CO2 molecules produced is 3 CO2 molecules x 2 pyruvate molecules = 6 CO2 molecules per glucose molecule.
Therefore, the correct answer is 6 carbon dioxide molecules.

Answers
Resistance exercise results in a(n) increase in the thickness of individual muscle fibers, and thus a(n) increase in the size of the muscle.
During resistance exercise, the stress placed on the muscles causes microdamage to the muscle fibers. In response to this damage, the body initiates a repair process that involves the synthesis of new proteins and the fusion of muscle fibers, resulting in an increase in the thickness or diameter of individual muscle fibers. This process is known as muscle hypertrophy.
Over time, repeated resistance exercise and muscle adaptation lead to an overall increase in muscle size and strength. The increase in muscle fiber thickness and muscle size allows the muscles to generate more force and perform better during subsequent exercise sessions.
