Consider a recessive mutation that results in a complete loss of gene function. If heterozygous individuals (mutant/wild-type) a

re phenotypically wild-type, then the wild-type allele would be described as being __________. See Section 4.1 (Page 107) .

Step2247 [10]3 years ago
6 0

Answer:

dominant

Explanation:

In this example, if heterozygous individuals that carry one wild type allele and one mutant allele (mutant/wild-type) are phenotypically wild-type, then, the wild-type allele is dominant. This is explained by the fact that wild-type is expressed, even when mutant allele produces a non-functional gene.

Katarina [22]
<span>There are four different examples of food chains in the movie "Finding Nemo".
1) Whales Eat Krill 
2) Sharks eat smaller fish 
3) Gulls (birds) eat anything they can 
4) Humans (fishermen) eat fish (implied through the harvesting or attempted harvesting of fish scene) 
5) Crabs scavenging for food from/along the pipes on the ocean floor 
6) Baracuda (scary fish) eats fish eggs at beginning of movie and Nemo's mom. 
7) The french shrimp cleans the tank by eating the algae and other build up. </span>

Electrons are brought to the electron transport system by the oxidation of
Viefleur [7K]

Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.

The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.

NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.

Researchers conducted an experiment to investigate the effects of a valinomycin treatment on skeletal muscle cells. Valinomycin
Mariulka [41]

The valinomycin treatment caused a decrease in the activity of the mitochondria.  

Explanation:

When valinomycin treatment was given, the rate of ATP production is reduced in the cells treated. Since mitochondria are involved in ATP synthesis, it clearly shows that valinomycin inhibits mitochondrial action.  

Valinomycin being a selective K+ ionophore, it can transfer potassium ions through selective lipid membranes. This can cause potassium effux in organelles like mitochondria leading to marked loss of potential of mitochondrial membrane and apoptosis in cells.

The effux of K+ ions forms a complex with valinomycin and slows down the mitochondrial part of ATP synthesis by reducing the proton-motive force, but does not block any oxygen electron transfer .

What process occurs as a zygote becomes a blastocyst? meiosis cleavage division fertilization ovulation
V125BC [204]

The zygote is split into the blastula after fertilization. The three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.

Fertilization :

The majority of animal reproduction is comparable to human reproduction. Additionally, animals create gametes for fusion. Gamete fusion, however, can happen inside or outside of the body.

Type of fertilization :

internal and external fertilization.

How does fertilization work, for insinstance ?

A reproductive technique that involved joining a male and a female germ cell—each with a single, haploid pair of chromosomes—to produce a diploid cell known as a zygote.

Pre-embryo is a collection of blastomeres formed by cleavage divisions.
