explain why the gametophyte plants live in moist habitats
Answer: Unlike the vascular sporophytes, the gametophytes have no vascular tissue at all. These gametophytes are therefore very small, and develop best in moist areas, where they can absorb water directly from their surroundings. Like the bryophytes, ferns and fern allies are still restricted to moist habitats.

Innate immunity and acquired immunity are both _____. See Concept 43.1 (Page 953) View Available Hint(s) Innate immunity and acquired immunity are both _____. See Concept 43.1 (Page 953) dependent on surface secretions from sebaceous and sweat glands, which give the skin an acidic pH that is unfavorable for bacterial colonization based on the trapping of microbes by mucus dependent exclusively on cell-mediated responses characteristics of all vertebrate animals dependent on tears, saliva, and mucous secretions that contain lysozyme, an enzyme that digests bacterial cell walls
Answer:
The correct answer is - characteristics of all vertebrate animals.
Explanation:
Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.
The only characteristic among these that present in both is that they both immune systems found in all vertebrates.

3. Which organism has DNA located in three organelles?
A. A sponge
B. A fern plant C. A flatworm
D. A bacterium
In a FERN PLANT, DNA is located in three different organelles (Option B).
Plants are organisms that have chloroplasts, mitochondria, and cell nuclei.In a eukaryotic cell, the genetic material (i.e., DNA) is mainly found in the nucleus, which is an organelle bounded by a double-membrane (bacteria don't have nuclei).However, mitochondria and chloroplasts are also membrane-bound organelles that have their own genetic material.Chloroplasts are only found in plants and algae (sponges and flatworms don't have chloroplasts).In conclusion, in a FERN PLANT, DNA is located in three different organelles (Option B is correct).

Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
Answer:
The type of mutation that causes this translation error is called deletion. Deletion occurs when a section of a DNA is deleted or lost. In cystic fibrosis, three nucleotides are deleted that results in the lost of phenylalanine

1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?
Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

Following fertilization and two rounds of cell cleavage, each of the four cells of a frog embryo has a centriole that is preparing for the next cleavage. The centriole in each of these cells can trace its origins back to the original centriole provided by the _______ prior to the first cleavage. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices secondary oocyte sperm ootid oogonium primary oocyte
Answer:
sperm
Explanation:
Centrioles are cylindrical organelles that play a major role during cell division, where they work to form the centrosome which duplicates and moves to opposite ends of the cell. The proximal centriole provided by the sperm cell mediates the separation of chromatids during the first cleavage of the fertilized egg. Upon fertilization, the proximal centriole forms the aster rays where microtubules act as a guide for the migration of the female pronucleus.

The Tibetans and Han Chinese share several genetic traits and DNA. However, the EPAS1 gene, which increases the ability of red blood cells to carry oxygen even in low oxygen environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is only common in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in three to five sentences.(4 points)
Answer:
When in higher altitudes, ticker blond has a tendency to cause problems like heart attack's, however the Tibetans have adapted to the high altitudes and this has made their blood thinner in order to keep them safe in the altitudes, including that it has low oxygen rates in the altitude therefore providing more oxygen in the bloods cells.
Explanation:
:D It's not my best explanation but I hope this helps <3.
Owing to the fact that ability of the redblood cells to to carry oxygen even in low oxygen environments is neccessary at high elevations, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.
What is natural selection?The term natural selection refers to the fact that organisms that are better adapted to their habitat will live longer and reproduce. Now we have to note that owing to the elevation at which they live, the people that possess this EPAS1 gene can cope with oxygen stress that could likely occur at a high altitude.
As such, the Tibetan population that live in higher elevations are found to possess the EPAS1 gene.

Natural selection leads to adaptations to __________ in an organism's environment. nonliving factors such as temperature and chemicals other living organisms abiotic and biotic factors water for aquatic organisms and the atmosphere for terrestrial organisms
Answer:
abiotic and biotic factors
Explanation:
According to the evolutionary theory proposed by Darwin, natural selection can be defined as the mechanism by which evolution occurs (i.e., the mechanism by which species change over time). An organism´s environment is comprised of abiotic (e.g., temperature, light, water, etc) and biotic (e.g., microbes, food availability, etc) factors. Adaptations refer to the phenotypic traits that increase the chance of survival and reproduction of an organism in its environment. Organisms better adapted to their environment are selected by natural selection to reproduce and thus perpetuate their genes across generations.

so it would be
Adenine to Uracil
Thymine to Adenine
Cytosine to Guanine
Guanine to cytosine
so we want to find the mRNA codon of the dna sequence CAT
Cytosine to Guanine (G)
Adenine to Uracil (U)
Thymine to Adenine (A)

How does the extinction of species affect humans?
A. Extinction generates new sources of medicine.
B. Extinction upsets the natural cycling of nutrients,
C. Extinction helps keep air and water clean.
D. Extinction makes the environment more pleasant.
Answer:
B. Extinction upsets the natural cycling of nutrients
The extinction of species affect humans as extinction upsets the natural cycling of nutrients. Therefore, option (B) is correct.
What do you mean by extinction of species?Extinction is the end of a sort of life form or of a gathering of sorts, normally an animal categories. The snapshot of annihilation is for the most part viewed as the passing of the last person of the species, albeit the ability to raise and recuperate.
As species go terminated, they are removed from the established pecking order. The animals that ate the species that has gone extinct must find new food or die. Other animal or plant populations could suffer as a result.
Habitat loss and degradation (primarily deforestation), overexploitation (hunting and overfishing), invasive species, climate change, and nitrogen pollution are the main modern causes of extinction.
