The following illustration shows a food web for a kelp forest off of the coast of California. What do you predict would happen to the kelp population if the sea otter population declined?




The kelp population would decrease: sea otters eat urchins, and urchins eat kelp.

The kelp population would increase: sea otters eat urchins, but not exclusively.

The kelp population would remain unchanged; sea otters do not eat the kelp.

The kelp population would remain unchanged: sea otters eat urchins, but not exclusively.

Answer:

Enzymes

Explanation:

Enzymes are proteins that act as biological catalysts, which speed up chemical reactions, to help support life. These enzymes help to perform important tasks such as breaking foods down into energy that the body can use.

Answer:

Basal metabolism,  Physical activity, Growth, Pregnancy and Lactation.

Explanation:

Basal metabolism,  Physical activity, Growth, Pregnancy and Lactation are the five factors that determine energy requirements in human beings​. To perform daily physical activities, we need a lot of energy which can be taken through breaking of food molecules as well as stored form of macromolecules such as fats and proteins etc. Energy is also needed for the metabolism and growth in humans beings because metabolism and growth processes needs energy.

Answer:

helps reduce intestinal inflammation by decreasing bacterial interaction with intestinal epithelial cells.

Answer:

There are no gram positive archaea because archaea lack peptidoglycan in their cell walls, meaning that the archaeic cell walls are more similar to gram negative bacterial walls, although they do show a greater variety of cell wall types.

EXPLANATION

Bacteria can be divided into gram-positive bacteria and gram-negative bacteria because of their cell wall composition.   The cell wall of gram-positive bacteria is made up of peptidoglycan which retains crystal violet stain and appears purple in color under microscope. The cell wall of gram-negative bacteria has an outer layer of lipopolysaccharide which do not retain crystal violet color and appear pink.   The cell wall of archaea is not made up of peptidoglycan but is made up of pseudo-peptidoglycan, therefore, no gram-positive archaea species is present on the earth.

Answer:

B) binding of a molecule to a binding site affects the binding properties of another site on the protein.

Explanation:

In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.

Answer:

Afforestation and national sanctuaries are two measures each to conserve natural vegetation and wildlife.

Explanation:

The natural vegetation and wildlife restoration is one of the main concerns that are essential for the development and growth of a country's biodiversity. Due to human land-use changes and migration of people, from one place to another with their cattle, lands are becoming deserted and grassland and forest land are declining.  

Answer:

Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. ... They can maintain different environments in a single cell that allows them to carry out various metabolic reactions

Answer:

Explanation: Akaryocytes, also known as akaryotes or acaryotes, are cells without a nucleus. The most common type of akaryocytes are viruses. The name is derived from the Greek prefix "a-", meaning "without" and the Greek "karyo-", meaning "nut" or "kernel". ... This cell biology article is a stub.

water velocity decreases

Explanation:

Sediment deposition will occur along the inner meander bends where the velocity is low.

Answer:

1,6 m / s ^ 2

Explanation:

De las leyes de Newton;

Fuerza = masa × aceleración

masa = 275 kg

Fuerza = 440 N

Aceleración = Fuerza / masa

Aceleración = 440N / 275Kg

Aceleración = 1,6 m / s ^ 2

Answer:

Between depths of tectonic plate boundaries and the outer core.

Explanation:

The rate of temperature increases below the Earth's surface is greatest between depths of tectonic plate boundaries and the outer core.  At the depth, some of the heat comes from the Earth's core while most of the heat comes from decay of radioactive elements, mainly uranium, thorium and potassium that is located in rocks of the crust. So we can say that the the increase in temperature with depth varies with the chemical composition and age of the rocks.

Answer:

Red tide occurs in patches of water where certain species of dinoflagellates flourish.

Explanation:  

Red tides refer to the noticeable microalgae proliferation that can be recognized for being a big spot in the sea of a characteristic coloration. This phenomenon is caused by two microalgae groups: diatoms and dinoflagellates, both part of phytoplankton.

Red tides occur when certain environmental factors -such as temperature, light, nutrients availability, ph, etcetera- favor the overproduction of these organisms. These species produce toxins that turn to be dangerous for other animal species that feed on them.

Because these microorganisms produce pigments, their accumulation on the sea surface can be noticed as reddish, brown, or greenish color spots of variable extension.

Answer:

Second choice; egg

Explanation:

Gametes are an organism's reproductive cells.

- Female gametes are called ova or egg cells

- Male gametes are called sperm

A tetrad consists of four chromatids, and a chromatid is one half of a duplicated chromosome.

An embryo is an unborn offspring (child) developing.

Answer:

Egg

Explanation:

The egg also known as ovum is the female reproductive cell.

Answer:

- I believe transcription.

-  Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein development.

- the end product is RNA.

I hope this helps! (pls mark brainliest) :)

Natural selection is that the process through which populations of living organisms adapt and change.

Many animals are well adapted to biotic and abiotic conditions due to behavioral, physiological, or structural adaptations that increase their chances of survival and reproduction.

.

Thus, we can conclude that the correct option is (b).

They are separate species because they cannot successfully reproduce.

which means they have different adaptation methods.

Answer:

B) A polysaccharide consisting of 2 types of monosaccharide units and cross-linking oligopeptides.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

Also, a unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

A bacterial cell is made up of peptidoglycan and its main function is to maintain the shape of a cell while preventing it from bursting due to osmotic pressure. Also, the bacterial cell inhibits the passage of larger molecules but allows the free movement (passage) of smaller molecules in the body of a living organism.

Basically, bacterial cell wall comprises a polysaccharide that's typically made up of two (2) types of monosaccharide units and cross-linking oligopeptides.

Answer:

Food costs more because there is less cropland

Explanation:

The amount of cropland available increases  is the most likely result of converting farmland to urban development. So, the correct option is A.

Urban planning is also called city planning, town planning, regional planning or rural planning which is defined as the technical and political process focused on the development and design of land use.

This development involves the transformation of an area into an urban state in various dimensions such as physical, geographical, economic and social through population and land use change. The conversion of farmland to urban development has many effects in terms of food security, reduced agricultural productivity, and agricultural labors.

The amount of cropland available increases  is the most likely result of converting farmland to urban development.

Therefore, the correct option is A.
