Which factor explains that in general, temperate and polar regions have less biodiversity than tropical regions
Answer:
Follows are the solution to this question:
Explanation:
The following are the two considerations demonstrating that there would be less biodiversity than the tropical areas in the Mediterranean climate as well as polar areas.
The first reason is all tropical areas experience drastic temperature variation. The second reason is early in the earth's history, the northern latitudes are inhabited.When you take antibiotics to treat bacterial infections, you often develop diarrhea and secondary infections as a consequence of the antibiotic therapy. Why, do you think, that happens?
Answer:
Why antibiotic-associated diarrhea occurs isn't completely understood. It's commonly thought to develop when antibacterial medications (antibiotics) upset the balance of good and bad bacteria in your gastrointestinal tract.
Explanation:
Holding your breath can only last a limited amount of time because you feel the need to start breathing again. The stimulus that drives this response is mediated by _______________.
A- Decrease in circulating O2 in blood
B- Increase in circulating O2 in blood
C- Decrease in circulating CO2 in blood.
D- Increase in circulating CO2 in blood
Answer: A - Decrease in circulating O2 in blood
Explanation:
To survive, the body needs to supply oxygen to the various cells so that they may use it for respiration. It uses blood as a conduit and acquires oxygen through breathing.
If a person stops breathing, it means that the cells will not be getting enough of the oxygen required to respire. When the oxygen levels get too low, the body will force the breathing to replenish oxygen and keep respiring.

Explanation:
Various hormones and factors (signal molecules) both influence and encourage mitosis in vertebrate animals. What processes might these signal molecules elicit in cells, and why might this signaling be important to homeostasis for an animal?
Answer:
Mechanisms enabling one cell to influence the behavior of another almost certainly existed in the world of unicellular organisms long before multicellular organisms appeared on Earth. Evidence comes from studies of present-day unicellular eucaryotes such as yeasts. Although these cells normally lead independent lives, they can communicate and influence one another's behavior in preparation for sexual mating. In the budding yeast Saccharomyces cerevisiae, for example, when a haploid individual is ready to mate, it secretes a peptide mating factor that signals cells of the opposite mating type to stop proliferating and prepare to mate (Figure 15-2). The subsequent fusion of two haploid cells of opposite mating types produces a diploid cell, which can then undergo meiosis and sporulate, generating haploid cells with new assortments of genes.

A key prediction/implication of evolutionary theory is that:
Answer:
-all species change gradually over time.
Explanation:
Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.
As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.
Which statement provides a possible explanation for the growth
pattern shown above?
1) O Manipulation of genes caused the movement of embryonic skin cells.
2)O Exposure to light stimulated the development of cells containing ozone.
3) Uncontrolled cell division occurred as a result of gene mutations
4)An immune reaction triggered the formation of excess blood cells.
Answer:
3) Uncontrolled cell division occurred as a result of gene mutations
Explanation:
Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.
Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like
UV radiation, chemical mutagens,infective agentsUV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.

20 POINTS PLEASE HELP Which is NOT an accurate statement about the structure of DNA? *
a double helix
b polymer made up of amino acid monomers
c a type of nucleic acid
d four possible nucleotides due to four different nitrogenous bases
e these are all accurate
Answer:
E. All choices are accurate representations of DNA.
Explanation:
DNA consists of a shape like a common known 'Double Helix' which is possible because it is made up of building blocks (chemical) known to us as nucleotides. Nucleotides are made up of monomers such as
phosphate groupa sugar groupOne of four types of nitrogen bases (Four types of nitrogen bases...adenine, guanine, cytosine, or thymine)DNA is a polymer which is, yes, made up of the monomers 'nucleotides'

Algae are photosynthetic protests that act similar to plants since they can make food for themselves es. What factors must be present for algae to grow densely or in abundance?
Answer:
Carbon dioxide, water, sunlight.
Explanation:
Photosynthesis uses the energy in sunlight to drive the reactions that produce glucose. These reactions are necessary for the algae to produce food, continue to survive, and grow.
As well as sunlight, photosynthesis requires carbon dioxide and water as reactants. The reaction produces glucose and releases oxygen as a byproduct.
The algae need an adequate supply of all of these reactants to grow in abundance.
Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall. After this sudden displacement of water, gravity acts to balance the water levels back, resulting in a tsunami.
Question 2 options:
True
False
Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall this is a correct statement.
What is tsunamis?A tsunami may initially look like a swiftly rising tide rather than a breaking wave. Due to this, it is frequently referred to as a tidal wave, despite the fact that the scientific community does not support this usage because it could create the mistaken impression that tides and tsunamis are causally related.
Tsunamis often consist of a sequence of waves that arrive in a "wave train" and have durations varying from minutes to hours. Large events have the potential to produce waves with tens of meters of height.
Although tsunamis only affect coastal areas, their destructive force can be immense and they can have a significant impact on entire on earth.
Therefore, Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall this is a correct statement.

Even though cancer genomes are overall hypomethylated, explain why some genes are hypermethylated in cancer cells. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. A. DNA repair genes B. OncogenesC. Cell Cycle stop genesD. Are not expressedE. HypomethylationF. HypermethylationG. Are expressed H. protein-coding genes______promoters will lead to reduced expression of the correspondent genes. Some genes such as____and_____need to be expressed. When they______, this can lead to cancer.
Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.
