To maintain this balance, the Hardy-Weinberg Equilibrium Principle states that a population should meet five main assumptions. There should be random mating, large population size, no mutation, no selection on the gene in question, and no gene flow in or out of the population.

Explanation:

Hypothalamus, pineal gland, and thalamus. Sensory abnormalities, visual-field deficiencies, and alterations in behaviour are all potential consequences of thalamic injury.

Thalamus, hypothalamus, subthalamus, and epithalamus are the four principal diencephalon subdivisions. Recognizing sensory stimuli and relaying sensory impulses to the cerebral cortex (apart from olfaction) are the main duties of the thalamus, which is the brain's biggest division.

One of the primary vesicles that create the brain during embryogenesis is the diencephalon. One of the three main germ layers, the ectoderm, is responsible for forming a neural tube during the third week of development.

Here are the structures that make up the diencephalon:

Answer:

Explanation:

D

The structure that is found in the cytoplasm of plant cell is vacuole. The correct option is A.

A vacuole is a cell organelle that is membrane-bound. Vacuoles are relatively tiny in animal cells and help to sequester waste material.

Vacuoles in plant cells aid in keeping water balance. A single vacuole can sometimes take up the majority of the interior space of a plant cell.

Within the cytoplasm of plant cells, there are also large, fluid-filled vesicles known as vacuoles.

Vacuoles typically make up about 30% of the volume of a cell, but they can fill up to 90% of the intracellular compartment.

Vacuoles are used by plant cells to regulate their size as well as turgor pressure.

Vacuole is a structure found within the cytoplasm of plant cells.

Thus, the correct option is A.

Explanation:

Capsids are made of protein subunits called capsomeres. ... Capsids are made of protein subunits called capsomeres, they protect the nucleic acid, they function in viral entry, and their shape is defined by the way in which their subunits are linked together.

All of these characteristics are accurate descriptions of viruses. Therefore option D is correct.

A. Viruses are considered to be non-living: Viruses do not possess the characteristics of living organisms, such as the ability to metabolize, grow, or reproduce on their own. They are dependent on host cells to carry out these functions.

B. Viruses possess a capsid and nucleic acid: A virus consists of genetic material, either DNA or RNA, enclosed in a protein coat called a capsid. The capsid protects the viral genetic material and facilitates its entry into host cells.

C. Viruses are obligate intracellular parasites: Viruses require a host cell to replicate and complete their life cycle. They cannot reproduce or carry out essential metabolic processes without infecting a host cell.

Explanation:

Explanation:

Glycolysis is the stage where glucose is broken down into 2 pyruvates (3 carbon compounds). This occurs in the cytoplasm and produces 2 ATP molecules. The pyruvates enters the mitochondria and enters the link reactions where it combines with co enzyme A (CoA). Decarboxylation ( removal of CO2) and dehydrogenation (removal of H) occurs here. Since CO2 is removed from the pyruvate it means a carbon is removed. This produces a 2 carbon compounds called acetyl. The acetyl compound is what combines with the CoA to form a compound called acetylCoA. This compound then enters the Krebs cycle.

The CoA co enzyme leaves and the acetyl reacts with a four carbon compound called oxaloacetate. This then forms a 6 carbon compound compound called citrate. A series of dehydrogenation and decarboxylation reactions occur to convert the 6 carbon compound back to oxalaoactate( the 4 carbon sugar). An ATP molecule is formed during one spin of the Krebs cycle.

The electron transport chain is where the reduced NAD (formed from dehydrogenation in glycolyisis, the link reactions and Krebs cycle) and Reduced FAD ( formed from dehydrogenation in the krebs cycle). molecules pass along a series of electrom carriers where they release energy that will be used to make ATP. Oxygen is the last electron carriers

more distant galaxies are moving away faster.

the shift towards red (Doppler effect like with sound on Earth) is the indication.

Explanation:

what did this have to do with biology ?

and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...

Explanation:

The food chain that correctly represents a pattern of energy transfer from producer to consumers to decomposer is:

Wetland: mosquito → fish → turtle → bacteria

In this food chain, the mosquito is the primary consumer that feeds on the producer (plant) - the energy from the plant is transferred to the mosquito. Hence option B is correct.

A food chain is a sequence of organisms in an ecosystem in which each organism feeds on the one before it and is, in turn, preyed upon by the organism after it.

The food chain represents the flow of energy and nutrients through an ecosystem, with producers at the bottom and apex predators at the top. The primary producers in a food chain are typically plants and algae that use sunlight to produce energy-rich organic compounds through the process of photosynthesis.

The fish is the secondary consumer that feeds on the mosquito, transferring the energy to the fish. The turtle is the tertiary consumer that feeds on the fish, transferring the energy to the turtle.

Finally, the bacteria act as decomposers that break down the dead organic matter from the turtle and other organisms, releasing the energy back to the environment in the form of nutrients.

Hence option B is correct.

Answer: Darwin was able to arrive at a conclusion that there was no relationship between the fossils of the ground sloth and the bones of the captured sloths that currently reside in South America.

Explanation:

Evolution is defined as the sum total of adaptive changes that have taken place over a very long period of time. It leads to the development of new species from earlier ones. Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist such as Darwin, have gathered a great deal of indirect evidence that supports the theory of evolution. These evidence comes from many sources including:

--> fossils records

--> biochemical similarities

--> molecular records

--> Comparative anatomy and

--> embryology.

FOSSILS RECORDS shows the existence of species that are now in extinct which lived on Earth during different periods of the planet's history. They provide evidence that organisms from the past are not the same as those found today due to adaptive changes that has occurred over a long period of time on the organism in order to survive in its environment.

There was no relationship between the sloths because of the difference in BONE MASS.
