Option d is Correct. Darwin introduced the concept of natural selection (survival of the fittest). This hypothesis contends that more people are created with each passing generation, and they fight for survival.
Phenotypic variation exists among individuals and the variation is heritable; those individuals with heritable traits that are better suited to the environment will survive and reproduce. Those individuals that can inherit the adaptations according to the change in the environment will survive, and the rest will die.
Differential reproduction is what is done in this situation. At the time of reproductive isolation, new species (evolution) will develop. Natural selection is demonstrated by the industrial revolution in the black peppered moth.

A mouse embryo is in the early stages of development, it seems cells are beginning to look different from each other, it is due to cell differentiation.
How does a mouse embryo develop?Cell differentiation is the process to develop a zygote into an embryo, and pluripotent stem cells are the undifferentiated cells, which develop into different cell lineages.
cells from the later blastocyst stage only give rise to two of the three cell lineages, because to the fact that embryonic stem cells are totipotent, whereas blastocyst cells are pluripotent.

In a plant, when the rate of respiration is greater than the rate of photosynthesis, what happens to the volume of carbon dioxide that is released?.
When the rate of respiration in a plant is greater than the rate of photosynthesis, the plant will release more volume of carbon dioxide (CO2) into the environment than usual.
Why carbon dioxide was released by plants into environment?This is because respiration is the process by which plants convert stored energy, such as sugars, into usable energy for growth and survival. During this process, CO2 is released as a byproduct. Overall, when the rate of respiration in a plant is greater than the rate of photosynthesis, the plant will release more CO2 than it is able to take in through photosynthesis, leading to a net loss of CO2 for the plant. This may not be favorable for the plant's growth and survival in the long term.
What is photosynthesis in plants?Photosynthesis, on the other hand, is the process by which plants convert light energy into chemical energy, using CO2 and water to produce oxygen and glucose. When the rate of respiration is greater than photosynthesis, the plant is using up more energy than it is able to produce, leading to a net loss of CO2. This can occur under conditions such as low light intensity, high temperatures, or water stress.

A scientist observes that the population of ch
turtles in a pond shows a clumped distribu-tion. Explain two reasons why turtles might show this kind of distribution.
The Resons for clumped distribu-tion are Clumped resources, social behavior and reproduction.
What is clumped distribution?A clumped distribution, also known as an aggregated distribution, describes individuals that are distributed in patches. This can happen if resources are distributed unfairly.
The Study of Hierarchies and Dominance Behaviors in European Pond Turtle
Research on intricate social connections in reptiles, especially in turtles, is still in its infancy and is frequently done on adults. Over their first year of life, researchers looked into how hierarchical social structures developed in hatchlings of the European Pond Turtle. and for seven months, they regularly examined the paired interactions of three small groups of turtles raised in a controlled environment. The goal of data analysis was to discover and describe the final hierarchical structures.
The sharing of spaces and activities by a steady group of people is a crucial prerequisite for the growth of solid social boundaries and complex relationships. Less than 20% of the 94 species of reptiles categorized as exhibiting social aggregation met the requirements for "stable social aggregation" in a review on the subject, according to Gardner et al. Chelonians are sort of a gray area in such a broad framework. There aren't many studies on social interactions and stable social structures, and those that do tend to focus on dyadic interactions between pairs of people, with an emphasis on agonistic behaviors rather than a broad perspective of potential hierarchical structures within the group itself.
Several studies on turtle and tortoise colonies in captivity appear to demonstrate that a few species can create linear hierarchies, which are not always correlated with biometric indicators or reproductive success.
Why do animals inhabit clumped environments?Resources are typically concentrated in tiny parts of a broader ecosystem, or individuals establish social groupings, which leads to clumped patterns. Because their habitats are not evenly spread over huge areas, the majority of species appear to have clumped distributions at large geographical scales.
How does the species benefit from clumped distribution?One benefit of a herd, community, or other clumped distribution is that it makes it easier for a population to spot predators early and from a farther distance, possibly mounting a successful defense.

When a tall plant TT in pea is crossed with another tall plant TT the probability of obtaining a dwarf plant is?
When a tall plant (TT) in pea is crossed with another tall plant (TT), the probability of obtaining a dwarf plant is 0%.
Both parents are tall plant (TT) which are homozygous dominant for the trait of plant height. This means that they both have two copies of the allele that codes for tall plant height (T). Since the allele for tall plant height is dominant, it masks the presence of any allele for short plant height (t). In this cross, both parents only have the allele for tall plant height, so all of their offspring will also have the allele for tall plant height.
This can be represented in a Punnett square shown in the attached picture. As you can see in the Punnett square, all the offspring will be TT, and will be homozygous dominant for the trait of plant height and will exhibit the dominant trait (tall plant height).

Where is the digestion food completed?
In conclusion, the digestion of food is completed in the small intestine, where most of the digestion and absorption of food takes place, and the large intestine, where most of the waste material is stored until it is eliminated.
Digestion is the process by which nutrients are broken down into smaller molecules that are then absorbed into the body. Food digestion begins in the mouth when food is chewed and mixed with saliva, which contains enzymes that begin the breakdown process. The food then passes through the esophagus, where it is further broken down and moves into the stomach. The stomach is where proteins are broken down into smaller proteins, and carbohydrates into simple sugars.
The next stop in the digestive system is the small intestine, where most of the digestion and absorption of food takes place. Here, proteins are broken down into amino acids, carbohydrates into simple sugars, and fats into fatty acids and glycerol. The small intestine also produces enzymes and hormones to further break down food. The products of digestion are then absorbed into the bloodstream through the small intestine wall.
