2. Describe how natural selection can occur in a population
Answer:
Natural selection requires variation between individual's genes. Mutations and sexual reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits of a species that are passed on to the next generation of offspring.
Hope this helps and good luck! = 0 ω 0 =
Answer:
Natural selection occurs during genetic mutations within the process of reproductions; these now altered or mutated genes cause the offspring to increase, as the organism undergoes the process of natural selection. This leads to evolution and new traits.
➲ Natural SelectionNatural selection is the process in which organisms whom are adapted to their environment tend to survive more and produce offspring more than usual. This process helps with more lifeforms become existent, and also proves the theory of evolution, which originated from Charles Darwin's evolution theory.

Which structure is at a different level of organisation from the other three?
7
A kidney
B liver
C neurone
D testis
Neuron structure is at a different level of organization from the other three. Correct option is C.
The other three options (A kidney, B liver, and D testis) are all organs, which are structures composed of multiple tissues that work together to perform specific functions in the body.
A kidney is an organ responsible for filtering blood, removing waste products, and regulating fluid balance in the body.
The liver is another organ that plays a crucial role in metabolism, detoxification, and the synthesis of important molecules.
The testis is the male reproductive organ responsible for producing sperm and male sex hormones.
On the other hand, a neuron (neuron) is a different level of organization. Neurons are the building blocks of the nervous system and function as individual nerve cells. They are specialized cells responsible for transmitting electrical and chemical signals throughout the body. Neurons come together to form nervous tissues, which, along with other types of tissues, make up the organs and systems that control the body's responses to various stimuli and help coordinate its functions.

What is the genetic problem that leads on to defective hemoglobin and shape of the rbcs in sickle cell anemia?
SCD is caused by a faulty gene known as the sickle cell gene. Sickle cell disease patients are born with two sickle cell genes, one from each parent.
What is the aetiology of sickle cell anaemia?Sickle cell disease (SCD) is a hereditary illness caused by a mutation in both copies of the HBB gene in an individual. This gene encodes a component of haemoglobin, the protein that transports oxygen in red blood cells. Because of the mutation, haemoglobin molecules clump together, resulting in sickle-shaped red blood cells.
Sickle cell disease (SCD) is a single-gene ailment caused by a single base-pair point mutation in the -globin gene that results in the amino acid valine being substituted for glutamic acid in the -globin chain.

The process of aerobic cellular respiration breaks down a glucose molecule in order to generate a large number of atp molecules. What type of pathway is this?.
A catabolic pathway is the kind of mechanism used by aerobic cellular respiration to break down a glucose molecule in order to produce plenty of ATP molecules.
The oxidation of biological fuels in the presence of an inorganic electron acceptor, such as oxygen, during the process of cellular respiration results in considerable quantities of energy that are utilized to power the primary production of ATP.
The citric acid (Krebs) cycle, an electron transport chain, chemiosmosis, and a transition process that results in acetyl coenzyme A are the four phases of aerobic respiration.
The maximum amount of ATP that might be produced by the aerobic oxidation of one glucose molecule is 38. Catabolic pathways convert nutrient molecules (Food: A, B, and C) into forms that the body can utilise (building blocks). During this process, energy is either released as heat or is stored in energy molecules for later use.

WRITE ABOUT A THEME: INTERACTIONS Giant lycophyte trees had microphylls, whereas ferns and seed plants have megaphylls. Write a short essay (100-150 words) describing how a forest of lycophyte trees may have differed from a forest of large ferns or seed plants. In your answer, consider how the type of forest may have affected interactions among small plants growing beneath the tall ones.
A lycophyte forest can be different from a forest of large ferns or seed plants because lycophytes have single leaves that separate them from all other plant groups. Its leaves, known as microphylls, have only one vein that runs the length of the leaf. All lycophyte plants are herbaceous, so no species grows wood, which would make this forest easily dependent on climatic conditions.
What is the difference between lycophytes and ferns?The most popularly known lycophyte is Selaginella. Selaginella are the best known lycophytes. In Botanical Science, the young leaves of ferns are called crosiers: they are born rolled up and resemble the shape of a staff or cane. When adults are called frond.

Why could it be dangerous to drink a very large amount of water in a short period of time?
Drinking very large amount of water in a short period of time can result in water intoxication.
Water Intoxication also referred to as water poisoning, is a disruption of brain function brought on by excessive water consumption.
The amount of water in the blood rises as a result. This can dilute the electrolytes, notably sodium, in the blood.
Medics refer to the condition as hyponatremia if sodium levels are less than 135 mmol/l.
The balance of fluids inside and outside of cells is maintained in part by sodium. Increased water intake lowers sodium levels, which causes cells to expand as fluids move from the exterior to the interior of the body.
This can be hazardous and even fatal when it affects brain cells.
