If Superman gets his powers from earths sun how does he have powers at night?

Which of the following is not a characteristic of all living organisms? A)energy utilization B)complex yet organized C)capable o

muminat

<em>Lets take a look at all the choices:</em>

A) Energy utilization

All organisms require energy to survive. That question is out for sure!

B) Complex Yet Organized

All living organisms are complex, and if they weren't organized, well, they wouldn't exist or they would have some serious problems!

C) Capable of Self-Reproduction

Simple: Not all organisms are able to reproduce asexually, for example, humans. We do not reproduce asexually. Therefore it is not a characteristic of <u>ALL</u> living organisms

D) Composed of Multiple Cells

No-brainer! All living organisms are composed of multiple cells!!!!!!!!!!!!

Therefore, the answer is C) Capable of Self-Reproduction

Enzymes antibodies and clotting compounds are made of

lys-0071 [83]

<span>Enzymes antibodies and clotting compounds are made of proteins, in which these proteins generally exist in different forms and a common example of it are the amino acids. To add up, these enzyme antibodies aids the immune system by serving as a catalytic antibody producing a hapten molecule.</span>

How does a decrease/decline in a top predator impact biodiversity in an ecosystem?

vivado [14]

Answer:

Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species

Please find the explanation below

Explanation:

In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.

A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.

Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.

In humans, there are four blood types: A, B, AB and O. Each parent can give their offspring one of three blood type alleles, IA

Delvig [45]

Answer: One parent is IAi and the other parent is IBi

Explanation: As this trait is codominant, the child can inherited IA, IB or i.

Tina has type O, which means she is ii and her sister is AB, so her genotype is IAIB. Now, to have a child with a recessive trait both parents has to carry at least one allele for the recessive, i. Rosa is type AB which means she had to have inherited one allele IA from one of her parents and the other IB from the other parent. Thus, one parent is IAi and the other is IBi.

Explain the role of lipids, carbohydrates, and proteins in the cell membrane.

koban [17]

Lipids provide structure - allow the selective diffusion. Proteins provide structure - involved transport - involved in cell adhesion. Carbohydrates are involved in cell recognition - receptor complexes.

<h3>What is the function of lipids, carbohydrates, and proteins in the cell membrane?</h3>

The cell membrane is composed of a lipidic bilayer, cholesterol, proteins, and glucans incrusted in between.

⇒ Lipids

Phospholipids are amphipathic molecules.

They have hydrophilic heads facing the exterior and the interior of the cells and hydrophobic tails that arrange against each other in the interlayer space.

Lipids can easily change places with other lipids by lateral diffusion and transversal diffusion.

Their function is to provide structure to the membrane and allow the diffusion of some selected small molecules.

⇒ Cholesterol

These lipidic molecules play a significant role in membrane formation and structure. They are embedded in the membrane in between phospholipidic tails.

⇒ Carbohydrates

Carbohydrates are significant energy store molecules.

Carbohydrates get attached to lipids and proteins on the outer side of the membrane (glycolipids and glycoproteins).

Complexes protein-carbohydrate are used to identify and differentiate the cell and work as receptors.

Carbohydrates are also involved in cell adhesion.

⇒ Proteins

Among the proteins, we can find integral proteins and peripheric proteins.

Integral proteins are permanently associated with the membrane. They accomplish many different functions such as substances transport, cellular receptors, and cellular adhesion, among others.

According to how they are incrusted in the lipidic bilayer, integral proteins might be,

→ Transmembrane proteins ⇒ they cross the two lipid layers of the cell membrane.

→ Monotypic integral proteins ⇒ they can be found tied to one of the lipidic layers.

Integral proteins provide structure to the plasmatic membrane.

Periferic proteins are in the internal or external surface but not incrusted in the membrane.

In conlusion,

Phospholipids are the basic elements of the cell membrane. They are arranged in two layers, and thanks to their motion properties, they allow passive transport (diffusion) of some substances.

Proteins provide structure, are involved in facilitated and active transport, and are involved in cell adhesion.

Carbohydrates are involved in cell recognition and in receptor complexes.
