Answer:
Genes come in different versions, otherwise known as alleles, with dominant alleles being expressed over recessive alleles (one stronger than the other in terms of traits and etc). Recessive alleles are only expressed when no dominant allele is present. Color of the eyes, for example is allele A is brown color eyes and B is blue color eyes, and assume that A is the dominant then that relationship will prove A to be the simple dominant and B the recessive.
how did eukaryotic cells evolve prokaryotic cells?
Answer:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes (endosymbiosis) is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
Explanation:
Both mitochondria and chloroplasts are similar to bacteria in size, and like bacteria, they reproduce by dividing in two.

Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

Using the genetic code, which of these events can happen?
mRNA can be made into tRNA.
DNA can be made into mRNA.
RNA can be copied before mitosis.
A polypeptide can be made into mRNA.
Answer:
...
Explanation:
.The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In what year did the human genome get completely decoded
Answer:
In 2003, an accurate and complete human genome sequence was finished two years ahead of schedule and at a cost less than the original estimated budget.
Explanation:
The school district wanted to determine whether the more expensive floor wax (Brand A) was better than the cheaper (Brand X) floor wax at protecting its floor against scratches. One liter of each brand of floor wax was applied to each of 10 test sections of the cafeteria floor. The test sections were all the same size. Ten other test sections received no wax. After 4 weeks the number of scratches in each of the test sections were counted.

Why is it important that the DNA is replicated during the S phase of interphase
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Which word best describes how many alleles there are for most genes: one, two, or multiple?
Answer:
Since humans are diploid they have two alleles for every gene.
Index fossils come from types of organisms that lived during only a relatively short period of time, were abundant, and
were widespread geographically. Index fossils can therefore used to determine the relative age of rocks found in
different areas. Index fossils help to match
A)
fossils from land and sea.
B)
rock layers from different areas.
plants to the animal life that ate them
D)
sedimentary rocks with igneous rocks formed at the same time.

Hemoglobin, insulin, albumin, an maltose, which are composed of chains of amino acids, are examples of
Answer:
Proteins
Explanation:
These are all examples of proteins
As a protein, insulin is made up of two chains A and B each of these chains have 21 and 30 amino acids.
As a protein, haemoglobin has 4npolypeptides chains. Each of these chains have greater than 140 amino acids. The chains are attached to a heme group.
Albumin is also a protein. It's composition is about 69% of blood protein. It is made by the liver.
Maltose is a disaccharide

Very small populations of island foxes are much more threatened by certain diseases than are very large populations of foxes.
Which statement is the best explanation of this difference?
Large populations are made up of stronger individuals than small populations.
Small populations are more easily attacked by viruses.
Large populations can move away from disease sources.
Large populations are more likely to have have greater genetic variation
Answer:
Explanation:
Following guidance from the Centers for Disease Control and Prevention ... Although the island fox is one of the smallest canids in the world, it is the largest ... The island fox is one third smaller than its mainland ancestor the gray fox. ... was able to reverse the certain extinction of an endangered population.

an adult
animal's body is
water?
15%
75%

90%
Answer: an easier distribution of body fluids to remember is the 60:40:20 rule: 60% of body weight is water, 40% of body weight is ICF, and 20% of body weight is ECF (see Fig. 1-1). Many clinicians use 20% as an estimate for ECF when calculating fluid therapy needs for their patients.

Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse then receive a responding pulse from the heart
True or False?
Answer:
true
Explanation:
i looked in my book for this
Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.
What is the heart's electrical signal?The heart has the SA node that autonomously originates the signal, and then the AV nodes receive that, and then the signals are transmitted to the ventricle and the heart contracts. In this process, the heart's electrical signal travels through the atrium and ventricle, and when the device measures the signal, the tiny electrical pulse is received by the device, which shows the electrical nature of the heart.
Hence, electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.
