Albinismisar are genetic condition that inhibits the production of melanin,or pigmentation,in the skin and hair. People born wit

h albinism are unusually susceptible to sun burn, melanoma, and a range of other health issues that are generally connected to excessive exposure to the sun. The statements above, if true, provide the most support for which of the following conclusions?A) People born with albinism develop other biological protections against melanoma and other sun-related health issues.B) Humans with a high production of melanin can easily ignore health issues related to exposure to the sun.C) When a non-albino person gets sunburn, the amount of melanin produced by that person decreases.D) In humans, melanin plays a role in protecting the skin from developing sunburn and other sun-related ailments.E) It is not possible for a person born with albinism to adopt other artificial protective measures against excessive exposure to the sun.

Answer:

D) In humans, melanin plays a role in protecting the skin from developing sunburn and other sun-related ailments.

Explanation:

From the statement given that is the best option, you can infer. The ones that talk about the protection of people with albinism are not correct because the statement is not referring to that topic.

While option B that states that humans with melanin can ignore health issues related to exposure to the sun is wrong. Because in the last part of the statement it says that the ailments stated are related to excessive exposure to the sun. People with albinism are very susceptible but that not infer that people with melanin are not capable of catching those problems. They only have more protection because of the melanin.

I hope this answer helps you.

Answer: German scientist Alfred Wegener

Explanation: <em>In the early 1900s, the German scientist Alfred Wegener noticed that the coastlines of Africa and South America looked like they might fit together. He also discovered evidence that the same plant and animal fossils were found along the coasts of these continents, although they were now separated by vast oceans.</em>

Is it possible to have a knockout mutant plant that shows no visible phenotype that is different from the wild-type plant?
joja [24]

Answer:

Molecular genetic approaches to the study of plant metabolism can be traced back to the isolation of the first cDNA encoding a plant enzyme (Bedbrook et al., 1980), the use of the Agrobacterium Ti plasmid to introduce foreign DNA into plant cells (Hernalsteens et al., 1980) and the establishment of routine plant transformation systems (Bevan, 1984; Horsch et al., 1985). It became possible to express foreign genes in plants and potentially to overexpress plant genes using cDNAs linked to strong promoters, with the aim of modifying metabolism. However, the discovery of the antisense phenomenon of plant gene silencing (van der Krol et al., 1988; Smith et al., 1988), and subsequently co‐suppression (Napoli et al., 1990; van der Krol et al., 1990), provided the most powerful and widely‐used methods for investigating the roles of specific enzymes in metabolism and plant growth. The antisense or co‐supression of gene expression, collectively known as post‐transcriptional gene silencing (PTGS), has been particularly versatile and powerful in studies of plant metabolism. With such molecular tools in place, plant metabolism became accessible to investigation and manipulation through genetic modification and dramatic progress was made in subsequent years (Stitt and Sonnewald, 1995; Herbers and Sonnewald, 1996), particularly in studies of solanaceous species (Frommer and Sonnewald, 1995).

Angiosperms do not need water for fertilization. Why? (3 points) Group of answer choices Flagellated sperm travel to the ovary i
astraxan [27]

Answer:

A pollen tube grows from the pollen grain into the ovary

Explanation:

Water is needed for fertilization in several plant groups because the sperm needs to swim to meet the non-motile eggs of the female organs.

<em>However in angiosperms, the pollen germinates and a structure known as pollen tube which contains the male gametophyte (sperm) grows into the ovary where the ovule is located and the male gametophyte is deposited in the ovule to initiate the fertilization process.</em>

<em>Hence, water is really not necessary for fertilization in the angiosperms.</em>
