Describe movement of molecules to maintain a healthy cell environment. Explain in details
Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.

1. Environmental scientists have become concerned that Maryland's
precipitation is too far from neutral to be safe for healthy aquatic
ecosystems. What property of water would they test?
Answer:
pH
Explanation:
The pH of a solution refers to the acidity or alkalinity of the solution. The solubility of some ions that are dissolved in a water body depends on the pH of the water. Sudden changes in pH could lead to sudden precipitation of substances from the water.
Hence, Maryland's precipitation may be monitored by environmentalists if they can observe the pH of the water in the course of searching for the possible cause of the precipitation occurring in the water body.

A scientist observes that a certain trait is determined by a single gene.
An organism inherited one version of the trait from one parent and
another version from the other parent. Both versions of the trait are
expressed in the phenotype of the offspring. Which pattern of
inheritance best classifies the observed trait?
Answer:
Codominance
Explanation:
Codominance occurs when both alleles participation in the expression of the genotype of an offspring, such as a flower with patches of different colours, each coming from a different allele.

Highlight all the atoms of the four functional groups, but do not highlight any bonds. When you click on each atom, it will change color. To deselect an atom, click on it again. Before you submit, check that you have not selected any bonds.
Hi. You did not submit any image, table or description of a molecule for the functional groups to be pointed out. This makes it impossible for your question to be answered. However, I will try to help you as best I can.
A functional group is a set of atoms of different chemical elements that take the place of a hydrogen atom that was part of a hydrocarbon (it is a molecule composed of carbon and hydrogen atoms). The most common functional group is −OH, but you also often encounter −SH, −NH2, and −OPO2−3 functional groups.

influenced factors. The graph depicts the changes in biodiversity at present and in ten years (predicted). Which statement(s) below
are supported by the graph? Choose ALL that apply.
A)
Climate change will increase the loss of biodiversity at a greater rate than
pollution
Invasive species will have a greater impact in loss of biodiversity in ten
years than pollution
B)
C)
"Habitat degradation is and will continue to be the leading cause of
biodiversity loss in the Mediterranean Sea.
D)
The loss of biodiversity in the Mediterranean Sea will increase for nearly
every factor over the next ten years.
E)
Exploitation of species in the Mediterranean Sea will lead to the greatest
decline in biodiversity in the area in ten years.
Scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.
What is the significance of the loss of biodiversity in the Mediterranean?Biodiversity is low in almost every region of the world due to rapid urbanization, which has resulted in the rapid loss of plants and animals as well as a decline in their numbers due to habitat loss, and they are further impacted by climate change.
Hence, scientists have made estimates of the loss of biodiversity in the Mediterranean Sea, and this is due to human interference, climate change will increase the loss of biodiversity, habitat degradation, and exploitation of species, so answers A, C, D, and E are all correct.

Discuss how a soil, a natural body, differs from soil, a
material that is used in building a roadbed.
Answer:
Soil is a material made up of gases, organic substances, water, and microorganisms. This material may be used in building a roadbed and is often referred to as dirt. In comparison, a soil is a natural body that is three-dimensional much like a lake or mountain.
Explanation:
Hope this helps
Gases, organic materials, water, and microbes are all components of soil. This substance, which is frequently referred to as dirt, can be utilized to construct a roadbed. In contrast, the soil is a three-dimensional natural structure similar to a lake or a mountain.
What is soil?Soil is the loosely packed organic or mineral material that makes up the Earth's immediate surface and acts as a habitat for land plants. The unconsolidated organic or mineral matter that has been exposed to relief-conditioned macro- and microbes operating on parent material throughout time, as well as genetic and environmental factors such as climate (including water and temperature effects). A product-soil is distinct from the source material in many ways, including in terms of its physical, chemical, biological, and morphological qualities.This is how natural soil is different from the material used in constructing roadbeds.

What is the function of the class of macromolecules represented in the following diagram
Answer:
lods ayarn na:)
Explanation:
The four classes of biological macromolecules are (1) Proteins, (2) Lipids, (3) Carbohydrates, (4) Nucleic Acids.
Proteins are made up of amino acids linked by peptide bonds. They have multiple functions, depending on the number of amino acids and its specific sequence. They serve as major workers composing motor and structural elements in the cell. They can also function as catalytic proteins (enzymes), as well as helpers for storage, signal, transport, reception, defensive, and contractile tasks.
Lipids are made up of fatty acids (a carboxylic acid with a hydrocarbon chain + terminal carboxyl group) and glycerols (organic compound made up of multiple hydroxyl groups). They are a hydrophobic compound that are used for energy storage, thermal insulation, protection, and chemical messengers. Lipids also regulate membrane permeability and aid in fat soluble vitamin production.
Carbohydrates are made up of monosaccharides which build up a polysaccharide (carbohydrates). Monosaccharides are basic sugars which cannot be broken down anymore by water (glucose, fructose, galactose). Carbohydrates' major functions include energy provision, blood glucose regulation, biological processes recognition, and breakdown of fatty acids for ketosis prevention.
Nucleic acids are made up of nucleotides which are organic molecules that forms the Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). Their structure consists of a nitrogenous base, pentose, and an attached phosphate group. The function of nucleic acids are the creation and storage of genetic information.

In 2012, excitement rippled through the scientific community with the discovery of an enzyme that appeared to be, just maybe, a powerful new tool for combating Alzheimer’s. At the Mayo Clinic in Florida researchers identified a gene, BACE2, which appeared to destroy beta-amyloid — a protein, then understood to be toxic, which is found in clusters in the brains of people living with Alzheimer’s. Alzheimer's is often diagnosed by measuring the amount of buildup of this protein. A large amount of it is an indicator of the disease. People with this buildup often do not have enough of the BACE2 enzyme created naturally in their body. If a way to synthesize this enzyme artificially or to prompt the body to create more were discovered, it could be hailed as a cure for Alzheimer's. How does the BACE2 enzyme work?
Answer:
BACE2 cuts both beta-amyloid and beta-amyloid precursor protein.
Explanation:
What makes BACE2 so effective in fighting Alzheimer's is its efficiency in cutting both beta-amyloid and the protein that develops it. There are other enzymes, which have the ability to break down beta-amyloid, but BACE2 is the only one that breaks it down into such small pieces that it completely destroys it. Furthermore, BACE2 is able to break down the beta-amyloid precursor protein, which prevents the formation of beta-amyloid from taking place.
