hout returning to the surface. Which of the following correctly describes this difference?
Whales need less energy than humans. Whales gather energy from their environment better than humans. Whales are able to conserve oxygen better than humans. Whales have cells that produce energy differently than humans.

The right answer is Whales are able to conserve oxygen better than humans.

As the duration of the dive of some whale species can reach more than one hour, they use other means to breathe. In vertebrates, myoglobin, a protein, transports and stores oxygen in muscle tissue. It works like hemoglobin that carries oxygen in red blood cells. It is also myoglobin concentration very strong that makes their flesh bright red color, almost black. Thus, whales use the oxygen stored in the muscles to dive for long periods.

Tju [1.3M]

Answer:

All the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

Explanation:

Given

Tallness ( T) is dominant to dwarfness (t)

Red (R) flower color is dominant to white (r)

It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance

Genotype of dwarf red snapdragon is RRtt

Genotype of a plant homozygous for tallness and white flowers is rrTT

The punnet square representing the cross between RRtt and rrTT is as given below-

Rt     Rt         Rt     Rt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt

rT RrTt      RrTt RrTt    RrTt  

Thus all the offspring have genotype RrTt

Phenotype is Pink and tall snapdragon

How does the tilt of Earth's rotation axis affect Earth's weather?
nikklg [1K]
I'm no Eisten, but from what I remember when I was in middle school. The Earth's rotation axis affect Earth's weather for seasons. The seasons change (weather) depending on the amount of sunlight as earth revolves around the sun.

What is the cause of the hydranencephaly? Select one: a. Aqueductal stenosis b. Subaranchoid stenosis c. Overproduction of CSF d
Dennis_Churaev [7]

Answer:

The correct answer is d.

Explanation:

Hydranencephaly is a rare congenital anomaly characterized by the absence and replacement of the cerebral hemispheres by cerebrospinal fluid and necrotic remains, with preservation of the membranes (leptomeninges), within a skull of normal capacity and shape. It is the most severe form of cortical destruction cerebral bilateral and is considered an extreme form of porencephaly (focal cystic cavity). It mainly affects the territory of the internal carotid artery and middle cerebral artery, with preservation of the territories supplied by the vertebrobasilar arteries. The most accepted etiology is carotid vascular insufficiency, due to multiple causes (bleeding, placental thromboembolism, arteritis, vascular malformations, among others).

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
