Answer:
Explanation:
Ethology is a branch of zoology in which zoologist study about the animal behaviour. Ethologists adopt a comparative method to study the varied form of animal behaviour ranging from - Sexual selection, aggression, co-operation between two organism, kinship etc.
Researchers study about both the classical behavior patterns (FAPs – Fixed action patterns) as well as the adaptive changes in behavior brought in by the evolution.

Answer:
Yes, the population can evolve differently with resistance gene to the HIV
Explanation:
AIDS is a deadly disease caused by the Human immunodeficiency virus. The HIV infection ultimately results in the death of the host and the cases are increasing every year.
If in the population of the area affected with the HIV AIDS develop some resistant gene to the disease, therefore, the resistant gene will be passed on to the generation and the population will evolve differently as a measure or response of adaptation and natural selection.
The case of sickle cell anaemia with modified shapes of red blood cell in the population of Africa, a resistance mechanism to malaria can act as evidence to the HIV case.
Thus, Yes, the population can evolve differently with resistance gene to HIV is the correct answer.

The nucleus is often considered to be the cell's control center. 2. The cytoplasm consists of everything inside the plasma membrane of the cell. 3. The plasma membrane forms a barrier between the inside and outside of the cell. 4. The cytoskeleton is essentially a "skeleton" inside the cell. 5. The rough endoplasmic reticulum is covered with ribosomes. 6. Lysosomes use enzymes to break down foreign matter and dead cells. 7. Plant cells specifically have a cell wall, a large central vacuole, and chloroplasts.
1. The nucleus
The nucleus is often considered to be the cell's control center. It contains the cell's genetic material and directs the cell's activities.
2. The cytoplasm
The cytoplasm consists of everything inside the plasma membrane of the cell. It contains various Organelles and provides a medium for cellular processes.
3. The selectively permeable barrier
The plasma membrane forms a selectively permeable barrier between the inside and outside of the cell. It controls the movement of substances into and out of the cell.
4. The cytoskeleton
The cytoskeleton is essentially a "skeleton" inside the cell. It provides shape, structure, and support to the cell.
5. Ribosomes
The rough endoplasmic reticulum is covered with ribosomes. Ribosomes are responsible for protein synthesis.
6. Enzymes
Lysosomes use enzymes to break down foreign matter and dead cells. They are involved in cell digestion and waste disposal.
7. Plant
Plant cells specifically have a cell wall, a large central vacuole, and chloroplasts.
The cell wall provides structural support, the central vacuole stores water and nutrients, and chloroplasts are involved in photosynthesis.

Answer:
This question lacks options; the options are:
A) Crickets are inactive in October.
B) Do crickets like warm weather better than cold weather?
C) Crickets chirp more frequently as temperature increases.
D) Crickets chirp for many reasons, and temperature is probably one reason.
The answer is C
Explanation:
A hypothesis is a testable explanation given to an observed problem. The hypothesis aims at solving or answering a particular question or observation. A hypothesis, which is subject to testing via experimentation, explains how the independent variable affects the dependent variable.
According to this question, Will notices that crickets seem to chirp more frequently at night in June than they do in October. He then asks a scientific question based on this observation that goes thus: how do temperature changes affect how often crickets chirp?
The best hypothesis that explains this scientific question is "Crickets chirp more frequently as temperature increases" because it gives a predictive statement about how a change in temperature (independent variable) affects chirping in crickets (dependent variable).
