Hamsters are long haired if they have the genotype LL or Ll and they are short haired if they have the genotype ll. A long haired hamster is mated with a short haired hamster. Half of the offspring are long haired and half are short haired. This allows us to conclude that the long-haired parent hamster

Answer:

The crossed extensor reflex is a type of motor response that occurs to tactile stimulation of a lower limb. This, like other reflexes, is an indication of the proper integration and development of the central nervous system.

Explanation:

Stimulation on one side of the body can produce, in addition to the ipsilateral response. The crossed extensor reflex is a type of motor response, reciprocal innervation is involved: the flexor muscles of the stimulated limb contract at the same time that the extensors of said limb are inhibited. Coupled with flexion of the stimulated limb, the reflex produces an opposite effect in the contralateral limb: the extensor muscles are activated and the flexors are inhibited, this cross-extension reflex increases postural support during withdrawal of the painful stimulus.

Choice D

Explanation:

When you translate the RNA, you replace C’s with G’s (and vice versa) and A’s with U’s (also vice versa). So, you get GUU UUA CGC UAG. Then you read the codon chart to get your answer. Hope it helps :)

The sequence of the amino acids which is being produced when this RNA is translated is Val - Leu - Arg - Stop. Thus, the correct option is D.

Codon can be defined as the sequence of three consecutive nucleotides in the nucleic acids such as a DNA or RNA molecule which codes for a specific amino acid. Certain codons are responsible for the signal of the start or end of the translation process.

Codons are universal in nature throughout the different living organisms. There are about 64 different codons which codes for 20 standard amino acids in the cell. There are three stop codons in the genetic code which stop the process of translation of protein molecules including UAG, UAA, and UGA.

The sequence of the amino acids which can be produced when this RNA is translated 5'-CAA AAU GCG AUC-3' will be Val - Leu - Arg - Stop.

Therefore, the correct option is D.

Answer:

The correct answer is - 3.3 g/L.

Explanation:

It is known that if endogenous metabolism is not important then,

µnet = µmax = 0.693/doubling time.

Given:

doubling time = 6.5 hr, therefore,

µmax = 0.693/6.5 = 0.1/h

Formula:

First, maximum dilution rate Dmax,

Dmax = µmax*[S0]/{Ks + [S0]}.........(1)

Steady-state cell concentration, X

X = Yx/s{[S0] - KsD/(meumax - D)..........(2)

Solution:

Yx/s = 0.33 g/g-substrate;

Ks = 12 x 10-3 g/L; [S0] = 10g/L,

puting value in (1)

Dmax = 0.1 * 10 / (12 x 10-3 + 10)

= 0.1/h.

Now it is given that operating D is 1/2 of Dmax, therefore,

D in our case will be = 0.05/h

concentration of protozoa cells from equation (2).

Therefore, X = 0.33*{10 - 12 x 10-3 * 0.05/(0.1 - 0.05)} = 3.3 g/L.

Answer:

Nucleosomes in turn are wrapped into 30-nanometer fibers that form tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, unwound DNA in chromosomes would be very long.

The average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.

An average temperature may be defined as the annual mean temperature of any geographical location which is estimated approximately by the average temperature of the maxima and minima for the warmest and coldest months of the year.

It is the principle that the increase in the depth below the surface of the earth ultimately leads to the rising of average temperature. This is due to the process of apparent heat.

It may be possible that higher or lower temperatures also occur. but the average temperature at depth of 10 km of earth surface should approximately remain 200°C. It is a factual type of question.

Therefore, the average temperature at depth of 10 km of the earth's surface is 200°C. Thus, the correct option is A.

I think its b. Competition would increase. Wildfire would increase the scarcity of resources, causing individuals to compete at higher rates.

Explanation:

not 100% sure tho

Wildfires can immediately impact competition in a forest ecosystem because wildfires would increase resource scarcity, causing individuals to compete at higher rates.

In addition to destroying native vegetation and killing many wild animals, a forest fire can also cause serious financial damage and even endanger the lives of people and domestic animals.

With this information, we can conclude that wildfires can immediately affect competition in a forest ecosystem because wildfires would increase resource scarcity, causing individuals to compete at higher rates.

Answer:

bioaccumulation of chemicals is the problem concerning all living organisms. This is the result of dynamic equilibrium between the uptake and elimination. The extent to which bioaccumulation occurs determines the toxic effects which are manifested. In some cases, the mechanisms of protection from certain undesirable substances deposited in special sites, to prevent their participation in the metabolic reactions, have evolved. The knowledge on bioaccumulation enables to assess the risk related with the presence of various chemicals in the environment, food, and at workplace and to present quantitatively the ability to control the use and emissions of chemicals.
