How are viruses spread from cell to cell?

Biology
1 answer:
abruzzese [7]3 years ago
7 0

Answer:

Replicate itself into the cell host

Explanation:

Visus is made from a protein capsule and inside a fragment of RNA. Sometimes they also have some feet of filament to get attached to the cellular membrane.

Once attached, the virus injects its RNA into the cytoplasm and travels to the nucleus and insert this fragment of RNA into the cell DNA and start making copies of itself.

When the cell is full of virus, the membrane breaks and releases all the new virus to the neighbor cells, and the process starts again.

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
Sophie [7]

Answer:

a. purple allele (C) = 0.609, pink allele (c) = 0.391

b. purple homozygotes = 371, pink homozygotes = 153, heterozygotes = 476

Explanation:

Given -

Purple flowers - 847

Pink flowers - 153

The frequency of recessive genotype i.e

q^ 2 = \frac{153}{1000} \\q^ 2 = 0.153\\

Frequency of recessive allele i.e q is equal to

q = \sqrt{0.153} \\q = 0.391

As per hardy Weinberg's first equilibrium equation -

p + q = 1\\p = 1-q\\p = 1-0.391\\p = 0.609

Frequency of purple homozygous species

= p^2\\= 0.609^2\\= 0.371

Number of purple homozygous species = 0.371 * 1000= 371

Number of pink homozygous species = 0.153 * 1000= 153

Heterozygous species is equal to

(1-0.371-0.153)* 1000\\= 0.476 * 1000\\= 476

Karolina [17]

Answer:

B and C are correct

Explanation:

Gelatin also referred to as hydrolyzed collagen.collagen is a structural protein in animal and undergoes hydrolysis to form gelatin.

Gelatin appears as a translucent, colorless and flavorless food ingredient used as gelling agents in food, drugs and  cosmetics.

When dry it is bristle and becomes gummy when moist.

Gummy bears are known for their chewiness and gelatin gives them the chewiness.

what evidence indicated that orrorin tugenensis was bipedal? group of answer choices short, flat bones of the foot long neck of
Zielflug [23.3K]

The most significant relic of this species is an upper femur that reveals indications of bone development typical of a biped, indicating that Orrorin tugenensis individuals likely walked upright on two legs while simultaneously climbing trees.

A hypothetical early Hominin species called Orrorin tugenensis was identified in 2000 and is thought to have existed between 6.1 and 5.7 million years ago. How Orrorin is connected to contemporary humans is unknown. Although this remains the most popular theory of human evolution as of 2012, its discovery was used to refute the idea that australopithecines are human forebears. The name of the only classified species, O. tugenensis, comes from the Tugen Hills in Kenya, where the first fossil was discovered in 2000. The name of the genus Orrorin (plural Orroriek) means "original man" in Tugen. Twenty fossils of the species have been discovered as of 2007.
