What is Homologous evolution and Analogous evolution give its example !
Spam✔️
Homologous evolution means divergent evolution.
it is a type of evolution in which different species have common ancestor. for example if we take members of one species and put them in different environments then it is observed that there is some changes in the species according to environment
analogues evolution means convergent evolution
Answer:
Similar traits can be either homologous or analogous. Homologous structures share a similar embryonic origin. Analogous organs have a similar function. For example, the bones in a whale's front flipper are homologous to the bones in the human arm.
The size of pupils changes when moving from dim to very bright light. Explain how this change occurs?
Answer:
In dim light, your pupil expands to allow more light to enter your eye. In bright light, it contracts. Your pupil can range in diameter from 1/16 inch (1.5 mm) to more than 1/3 inch (8 mm). Light detected by the retina of your eye is converted to nerve impulses that travel down the optic nerve.

Q2.
Which stage of meiosis is illustrated above?
The diagram shows an example of a food web. What are common traits of the prey shown that help them survive? What might happen if the rabbit population suddenly shrank due to disease?
Answer:
Adverse effect on the animals.
Explanation:
If the rabbit population suddenly shrank due to disease, it will adversely affected the population of eagle, fox and coyote because these animals depend on them through feeding. Eagle, fox and coyote feed on the rabbit so if the population of rabbit decreases, then there will be scarcity of food for these animals and as a result decrease occur in their populations so we can say that adverse effect occurs on the population of eagle, fox and coyote.
can anyone help me with this question? Thank you.
Answer:
At B part.
Explanation:
At B part the nightfall will happen first because the B part is in the shade and will not present in front of the sun. When the earth rotates its own axis, the shaded part which is B comes in front of sun which means day time is started while on the other hand, the A part is in the shade and will experience nightfall so we can say that the nightfall occurs at B part of the earth.

What is the name of the supercontinent in Alfred Wegener’s continental drift hypothesis?
Answer:
Pangaea
Explanation:
Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.

Early in mitosis, the nucleus, nucleolus, and nuclear envelope begin to dissolve in preparation for cell division. In
which stage of the cell cycle is this process reversed?
Answer:
Telophase
Explanation:
During telophase, a nuclear envelope becomes apparent around the nucleolus of each sister chromatid, forming their nucleus before separation/cytokinesis.

Explanation:
The release of water from the of the cells caused the plant to wilt and droop. The in the plant's cells helps the plant to maintain its structure during this period of stress.
Answer:
Vacuoles are the first blank, while cell membrane is the second blank.
Explanation:
The release of water from the vacuoles causes a plant to wilt and droop; if the cells do not contain any water, the plant will wilt and droop.
Vacuoles are enclosed compartments in the solution that are filled with water, inorganic-organic compounds, and enzymes. It's a crucial organelle in the cell of a plant.
The cell wall, on the other hand, aids in the plant's structural preservation during times of stress.
the organelle responsible for inspecting and packing protein?
mitochondria.

Describe movement of molecules to maintain a healthy cell environment. Explain in details
Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.
which of the samples shown below are photosynthetic
Option B. Samples ACD Are photosynthetic
What does it mean to be photosyntheticTo be photosynthetic means to possess the ability to carry out photosynthesis, a vital process in which organisms, typically plants, algae, and some bacteria, use sunlight, carbon dioxide, and water to synthesize organic compounds, particularly glucose, and release oxygen as a byproduct.
Photosynthesis occurs in specialized cell structures called chloroplasts, which contain chlorophyll and other pigments that capture light energy. These pigments absorb light, primarily in the visible spectrum, and convert it into chemical energy through a series of biochemical reactions.
