Which of these is a way climate change positively affects organisms?

ArbitrLikvidat [17]

Answer:

Climate change positively affects organisms by providing them new habitat. 

Explanation:

Climate change induces changes in various parameters of an ecosystem like temperature, precipitation, soil properties etc. habitats may undergo changes that make it unsuitable for native organisms to live in.

But this new conditions may be favourable for some other kind of organisms to thrive and flourish.

For example, when temperature of a lake increases due to climate change warm water aquatic organisms find a new habitat in the lake. But this threatens the life of native cold water organisms of the lake. 

Thus climate change doesn’t bring any benefits to living world without harming one or the other group of organisms.

(a) Describe the process by which cells produce the FGF5 pre-mRNA , and include the location

Svetlanka [38]

Answer:

Explanation:

mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.

FGF5 is a gene that is encoded in the DNA.

A grandfather has an x-linked disease. His wife does not have the disease and she is not a carrier for it. What is the probabili

kotykmax [81]

There is 50% probability that their daughter's son will have the disease, because daughter chromosomes are XX , and the X from father will have x- linked disease, now in next generation the son will have XY chromosomes, Y is from father and X will from mother, now mother have two "XX", out of these two one carry x- linked disease, that means 50 percent chances of having disease in son.

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN

A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how

Wittaler [7]

Answer: The cell is eukaryotic because it has chloroplasts. A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria.
