Explanation:
Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Crocodile
The organism in the photo is a daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the daphnia environment, daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the daphnia allows the population to adapt to environmental change
Answer:
The characteristic of daphnia which allows the population to adapt to the environmental change is the short generation time.
Explanation:
As evident from the text, the maturity comes in 5 to 10 days and they reproduce for the next 2 months at a rate of 100 eggs every 3/4 days. This is a short generation time which makes the evolutionary changes easy and less time-consuming to incorporate.

Which of the following statements about energy in systems are true?
The amount of energy in a system must equal the amount of matter in the system.
Energy can be changed from one form to another.
When energy leaves a system, it is transformed into matter.
Energy can be transferred into or out of a system.
Answer:
When energy leaves a system it is transformed into matter
Explanation:
First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another.
Why should organisms that produce more offspring have a more likely chance of survival?
Answer:Organisms must struggle to get what they need to survive, competing against other organisms that want the same things they do.
Explanation:
Answer:
I will try to put this in the simplest terms I can:
If you think about it, organisms actually do not live that long. There are multiple cause and effect reasons, such as low resources, no food, extinction, and so on. Thus, organisms must produce offspring to keep their "family line" consistent.

If you cross an Aa individual with another Aa individual, what will the genotype ratio be in the next generation? What will be the phenotype ratio?
Answer:
Aa x Aa makes Aa because its a dominant gene. each square represents 25% so if u have 2 squares with Aa for example the ratio will be 2:4 (so 50%) if the gene is recessive then for the next generation it will go down to 25% unless another Aa allele is introduced in the next generation
Explanation:
Answer:
AA : Aa : aa Dominant : Recessive
Genotype ratio=> 1 : 2 : 1 Phenotype ratio=> 3 : 1

Which organelle converts sugars into energy?
A. lysosome
B. mitochondrion
C. nucleus
D. ribosome
The organelle that converts sugars into energy is the mytochondrion, which is the powerhouse of the cell, so the correct option is B. mitochondrion
Which organelle converts sugars into energy?The mitochondrion is often referred to as the "powerhouse" of the cell because it is responsible for generating energy in the form of adenosine triphosphate (ATP) through a process called cellular respiration.
During cellular respiration, glucose (a sugar) and oxygen are metabolized within the mitochondria to produce ATP, which serves as the primary energy currency of the cell. The mitochondria are present in most eukaryotic cells and play a crucial role in energy production.

A scientific study demonstrated that rat mothering behavior impacts the stress response in their pups. Rats that were born and grew up with attentive mothers showed low activation of stress-response genes later in life, while rats with inattentive mothers had high activation of stress-response genes in the same situation. An additional study that swapped the pups at birth (i.e., rats born to inattentive mothers grew up with attentive mothers and vice versa) showed the same positive effect of attentive mothering. How do genetics and/or epigenetics explain the results of this study
Answer and Explanation:
Regarding genetics, the results of the study show that the mother's genetic material does not influence the behavior of rats in times of stress or in the biological responses of rats to these stressful moments. This is because the mice inherited their mothers' genes, but did not show the same results in a stressful situation when they were raised with different mothers.
Regarding epigenetics, however, we can see that the mothers' behavior in relation to the care of rats managed to provoke epigenetic changes that prevented or stimulated the expression of genes linked to stress, in these rats. The rats that were raised with attentive mothers showed a low expression of stress-linked genes, regardless of the biological mother they had. In addition, it is possible to notice that this modification is permanent, since the rats presented this same type of response throughout their lives.

3.1.8 Cancer causing factors - Carcinogens
3.1.9 Cancer cells that do not spread - Benign
3.1.10 Replicated half of a chromosome - Chromatid
Explanation:
The division of the cytoplasm is known as Cytokinesis. It occurs during the later part of the division of the nucleus in both mitosis and meiosis. In Cytokinesis, the cytoplasm of a single parent cell divides in two to produce two daughter cells.
Cancer is a disease condition that results when the growth and division of cells is uncontrolled. It occurs as a result of changes to the DNA either due to environmental factors or heredity factors.
Metaphase is one of the four stages in mitosis. During mitosis, the chromatids which are joined at the centelomere line up at the middle or equator of the cell.
Centromere is a region in the chromosome in which sister chromatids are joined together to form a short and a long arm of the chromosome.
A tumour is a swelling of a part of the body due to the abnormal growth of cells in that part of the body. A tumour may have the ability to spread or not.
Cancers that originate in the skin or tissues lining organs is known as carcinomas.
In plants, meristematic tissues are responsible for growth as they consist of actively dividing or mitotic cells. Meristematic cells are present at the tips of roots,stem and branches.
Carcinogens are agents or factors that are able to cause cancers. They include such agents like chemicals, electromagnetic radiations, some viruses, lifestyle factors, etc.
Benign tumours refers to growths in tissues or organs of the body which are non-cancerous as they do not spread to other tissues or organs in the body.
A chromatid is one-half of a replicated chromosome present in the nucleus of the cell. Two chromatids are joined together at the centromere to form the chromosome.
