Explanation:

It was proposed by Theodor Schwann that animals were made of cells.

Although Robert Hooke (who coined the term “cell”) first noticed them in 1695, it wasn’t until 1839 that Theodor Schwann (author of “The Theory of Cells”) and Mattias Schleiden first proposed the idea that all living things are made up of cells.

An animal cell is an eukaryotic cell with a plasma membrane surrounding it. The cell has a membrane-binding nucleus and a liquid cytoplasm and does not have a cell wall like a plant cell. Animal cells are part of the kingdom Animalia.

Theodor Schwann coined the term cell theory and claimed that all living things are made up of cells and that cells were the smallest and most fundamental component of all living things.

Answer:

A. I, II, III, and V only

Explanation:

In genetics, an allele refers to the specific form of a gene, which encodes traits. These alleles are usually in pairs in a diploid organism i.e. an organism with two sets of chromosomes. According to Gregor Mendel,

- An allele can either be DOMINANT when the allele masks the phenotypic expression of its allelic pair while the allele that is masked is said to be RECESSIVE.

- Two alleles can also be CO-DOMINANT when the two alleles are neither dominant or recessive over one another but are simultaneously expressed in that particular gene.

- Alleles can also be INCOMPLETELY DOMINANT when one allele is not completely dominant over the other, hence, forms a third intermediate phenotype when in combination with the second allele i.e. in an heterozygous state.

Based on this, an allele can be dominant (I), recessive (II), codominant (III), and incompletely dominant (V).

The most correct option is the first option

Explanation:

A deer is an herbivorous animal that is usually preyed upon by many wild carnivorous animals like lions, tigers and leopards. Hence, when the population of these wild predatory carnivorous animals reduce, the population of the deer would increase because fewer of them would them would be killed by predators despite them (the deers) reproducing.

Note that a predator is an animal that feeds upon another animal (referred to as prey) of lower "strength".

Answer:

If the DNA of a cell is destroyed completely the cell would die i.e. cease to exist. A change in the DNA (germ-line mutation) would change the structure and/or functions of proteins in the cell.

Explanation:

The central dogma theory indicates that DNA is replicated to produce daughter cells. These daughter cells are then transcribed into mRNA (micro RNA) which are in turn translated into structural and functional proteins.

If the DNA is totally destroyed, no mRNA is formed and by implication, such a cell has no proteins. Now proteins are practically the "godfather" molecules in any cell, they maintain the selectively permeable cell membrane's integrity, they form the structural component of most cellular organelles, they are essential for transport of essential/toxic substances in/out of the cell, etc.

Looking at these functions, cessation of protein production is equivalent to cessation of cell life (apoptosis if DNA destruction is not stimulated externally).

A mutation (change in DNA) changes which protein is produced. A practical indication of this is when a single point mutation in hemoglobin produces sickle cell anemia!!

Answer:

The correct answer is - the sun.

Explanation:

When a plant is in initial stages there isgradual increase in  the mass of the plant which become later as a tall tree by the process of the phostosynthesis as it increase the storage of glucose or sugar in the tree. The mass of the tree by glucose storage is due to the carbon molecules of CO2 moleules.

Photosynthesis is the process that involves the trapping of the light come from the sun which is then converted in the cheical energy in the form of the glucose or the sugars.

The chemical energy present in the tall trees comes from the Sun.  

• Through the process of photosynthesis, the tall trees convert energy from the Sun, that is, light energy into the chemical energy.  

• The majority of this energy is stored in the trees in the form of compounds known as carbohydrates.  

• When animals consume trees and its components, they consume and absorb some of this energy, that is, stored as chemical energy into the compounds protein and fats.  

Thus, the green plants and trees are the source of energy, that is, used for various purposes. Through the process of photosynthesis, the light energy coming from the Sun gets converted into the chemical energy that gets stored as carbohydrates.

ATP synthase is a protein attached to the thylakoid membrane that helps synthesize ATP each time an H+ ion exits the thylakoid. Therefore, option A is correct.

The enzyme that produces ATP molecules is called ATP synthase. ATP synthases create ATP from its precursor, ADP. The cristae and inner membrane of mitochondria, the thylakoid membrane of chloroplasts, and the plasma membrane of bacteria all contain these enzymes.

It is a multi-component complex that crosses the mitochondrial inner membrane, the cell's power plants.

In order to manufacture ATP more effectively, the curvature of the mitochondrial inner membrane must be created by the interaction of the enzyme complex with fatty molecules. Therefore, option A is correct.

Lions are primarally carnivors because they only consume meat. Herbivores are animals that only consume plant like rabbits and Ominvores are animals that consumer both like humans., so consumer

Explanation:

A lion is a consumer. In ecological terms, a consumer is an organism that obtains its energy and nutrients by consuming other living organisms.

Lions are carnivores, which means they primarily feed on other animals. They are top-level predators in their ecosystems, preying on a variety of herbivores, such as zebras, wildebeests, and antelopes.

As consumers, lions play a vital role in regulating prey populations and maintaining ecological balance in their habitats. They are not producers or herbivores since they do not engage in photosynthesis or primarily eat plants.

Additionally, lions are not omnivores, which are organisms that consume both plants and animals.

c. the GTP-bound form of Gas, locking it in the active conformation.

Explanation:

The reason is that the toxin created by the enteric intestinal bacterium Vibro cholerae triggers an exorbitant amount of diarrhea by inducing the excretion of NaCl and enormous amounts of water into the bowel. The mechanism by that epidemic cholera toxin acts is ADP ribosylation of the Gs alpha monetary unit. This implies that G[tex]\alpha[/tex]s macromolecule protein exploits NAD, therefore protecting it within the active conformation.

Answer:

(a) The rate of oxygen consumption will decrease.

Explanation:

The rate of oxygen consumption will decrease due to the Potassium cyanide which inhibits both utilization of oxygen by the cell as well as ATP production. Cytochrome performs an important function in the mitochondria of the cell which is the production of ATP. Cyanide binds to the cytochrome and inhibits the ATP production that is performed by mitochondria of the cell. So Potassium cyanide decreases the rate of oxygen consumption in mitochondria.

Answer:

These injuries occur from a big accident.

Explanation:

I conclude that the person received these injuries from a big accident because the individual has many broken bones and this will happen only when a person experience a big accident such as hit by the truck or car etc. It is also possible that the person was killed by someone and before killing he beat the individual very badly as a result its bones were broken.

Fractures are defined as the dislocation or breaking of bones due to an injury or an accident. The fractures can be partial, closed, stable, or open.

The correct answer is:

While they were alive

The fractures having sharp edges, angled ends, and hinging can be caused when the person was alive.  

Perimortem fractures are those fractures that do not show any healing of fracture.

In the skeletonized remains of the human, the fractures have sharp edges, angled ends, and hinging.

The human remains do not show any healing, and therefore, were dead due to this injury or trauma.

Dark energy is a hypothesis by which the growing tendency of the universe to expand constantly is explained, with which it is inferred that this dark energy is a kind of inverse gravity, which instead of attracting repels the extremes of the cosmos expanding its size and dimension . Although its definition is very ambiguous and abstract, the truth is that it is a hypothesis that seeks to explain this physical behavior of the cosmos.

The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
