Explanation:
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.
SO you hopefully selected that an Allele is a form of a gene. BUT what is this really...
A. an allele is a protein that causes hair no hair in the guinea pig
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Answer:
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig
Explanation:
An organism that has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.
B. an allele is a length of DNA with a specific sequence of nitrogen bases that make a protein that results in Hair or No Hair on the guinea pig

how can we apply the principle of transpiration in producing clean water?
Explanation:
Transpiration is a process that involves loss of water vapour through the stomata of plants. The loss of water vapour from the plant cools the plant down when the weather is very hot, and water from the stem and roots moves upwards or is 'pulled' into the leaves.
Answer:
During photosynthesis, the layer of TiO2 absorbs light, breaking down toxic pollutants in the water, while the gold layer emulates the transpiration of a leaf and harnesses sunlight to evaporate the water at the surface. The resulting vapor condenses into completely-purified water.

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.

If a cell has a diploid number of 8 (2n = 8) before meiosis, how many chromosomes will be in each of the four daughter cells after meiosis II if one pair of homologous chromosomes experiences nondisjunction in meiosis I? Show how you got the answer by drawing out the process, starting with the diploid cell undergoing meiosis I (where nondisjunction occurs) and then meiosis II to get the four daughter cells.
Answer:
The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.
Explanation:
If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.
If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.
The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).
But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Explanation:
Crossing-over takes place between homologous chromosomes.
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.

The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics. The key can be used to classify each of the four animals represented below. Which answer choice shows the correct classification group for each animal? 1. Wasp = group D; Ant = group D; Tiger = group A; Bird = group B 2. Wasp = group B; Ant = group A; Tiger = group D; Bird = group C 3. Wasp = group B; Ant = group D; Tiger = group A; Bird = group C 4. Wasp = group D; Ant = group A; Tiger = group A; Bird = group B
Complete question:
The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics.
Dichotomous Key
I wings------------------go to II
no wings------------- group A
II feathers---------------group B
no feathers----------go to III
III two legs------------- group C
six legs---------------group D
The key can be used to classify each of the four animals represented below ⇒ wasp, ant, tiger, bird
Which row in the chart shows the correct classification group for each animal?
Row Wasp Ant Tiger Bird
(1) group D group D group A group B
(2) group B group A group D group C
(3) group B group D group A group C
(4) group D group A group A group B
Answer:
Row Wasp Ant Tiger Bird
(4) group D group A group A group B
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsExplanation:
When analyzing a dichotomous key, you just need to pay attention to the given descriptions and carefully observe the organisms you have.
The key describes specific morphological traits of each organism that are useful to differentiate it from other organisms. So all you need to do is to follow the instructions given in each step, and the key will guide you directly to the answer.
In the exposed example you have four organisms: wasp, ant, tiger, bird
The provided key gives you three steps: I, II, III.
Step I:
wings------------------go to II
no wings------------- group A
Here the key tells you to separate, from your group of organisms, the ones that have wings from the ones that do not have wings.
wasp and bird have wings → So you need to go to step IItiger and ant do not have wings → So they belong to Group AStep II:
feathers---------------group B
no feathers----------go to III
Now you only need to consider the bird and the wasp, which are the two organisms that have wings.
Here the key tells you to separate the one that has feathers from the one that does not have feathers.
Bird has feathers → So it belongs to the group BThe Wasp does not have feathers → So you need to go to step IIIStep III:
two legs------------- group C
six legs---------------group D
In this last step, the key takes you to two possible groups. But you only have one left organisms, which is the wasp. So what you need to do is to observe how many legs your wasp has. It is an insect, so it has six legs. The wasp belongs to Group D.
You do not have any organism that belongs to group C.
To sum up, according to the given information you could group the group of organisms as follows:
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsNEED AN ANSNER VERY QUICKLY

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.
