(1 Point)
O Digestive System
O Excretory System
O Respiratory System
O Circulatory System
O Lymphatic System
Can you plz help?
Answer:
respiratory system
Explanation:
The bronchi become smaller the closer they get to the lung tissue and are then considered bronchioles. These passageways then evolve into tiny air sacs called alveoli, which is the site of oxygen and carbon dioxide exchange in the respiratory system.

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.

what is meant by photosynthesis
Explanation:
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Answer:
The process by which plants turn carbondioxide and water into carbohydrates and oxygen using light energy trapped by chlorophyll, is called photosynthesis.

What is the role of complementary base pairing in the replication of DNA?
A It reduces the number of errors in the process of DNA replication.
B It introduces more hydrogen bonds between the nucleotides.
C It ensures that the replicated DNA is an exact copy of the parent DNA.
D It allows the replicated DNA to have a different nucleotide arrangement
Answer:
c. it ensures that the replicated DNA is an exact copy of the parent DNA
Explanation:
This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

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.
