Answer:
Two individuals mate, and each is capable of producing over 8 million potential gametes. The random chance of any sperm and egg coming together is a product of these two probabilities.
Pls someone help its a very easy question also don’t worry about the dot I accidentally did that
What is the optimal pH that this enzyme functions at? And What is the optimal temperature that this enzyme functions at?
Answer:
Optimum Temperature is 35°C
Optimum PH is 7.0.
Explanation:
The optimum temp of enzymes is 20-35°c. They become inactivated at very low temperature and denatured (destroyed) at very high temp i.e. greater than 45°C. Low molecular weight enzymes are comparatively more heat stable.
The optimum pH of most enzymes is pH 7.0 (neutral pH).
your slide is in focus but you cannot see anything, what maybe the possible problem
Answer:
The correct answer would be - using a lens that is too high powered and thus you may be too focused on the specimen.
Explanation:
The possible scenario for this case where the slide is in focus but can not see anything could be either specimen is not under the lense or too focused on the specimen by using a very high-powered lens.
In a very high-powered lens, the lens becomes over-focused and the specimen does not look in the field of view of the lens, in such case, an individual should ower the power of lense.

How will the temperature inside the car feel?
Hint: Akbar wonders if what happens in his car is similar to the greenhouse
effect.
Predict the temperature of the air inside the car.
Colder than the outside air.
Warmer than the outside air.
Exactly the same as the outside air.
Answer:
Predict the temperature of air inside car because we can use cooler to cool and if we close all windows it will be hot inside.
In cats, the gene for Calico (multicolored) cats is an x-linked trait that is
CODOMINANT. Females that receive a "B" and an "R" gene have black and orange
splotches on white coats. Males can only be black or orange, but never calico.
A female calico's genotype is XBXR
Cross a female calico cat with a black male. (Complete a Punnett square)
What are the results of the cross?
25% Black and male, 0% Calico Male, 25% Calico female
50% Black and male, 50% Calico female.
50% Orange and male, 50% Female Black

1/2 = 50% of males will be black, XBY 1/2 = 50% of males will be orange, XRYred-green color blindness is an x-linked recessive disorder. if the mother is RGCB and the father has normal vision, what are the changes for daughters and sons to hae the trait
Answer:
The correct answer would be -
RGCB daughter - 0%
RGCB sons - 100%
Explanation:
Red-green color blindness is a sex-linked recessive disease that means it will only express in absence of the normal allele that is present on X-chromosomes. As it is known that males have only one X-chromosomes therefore, the chances are more in males to be affected in presence of the recessive gene. In this given case women s RGCB and man has normal vision. The genotype of women would be both recessive alleles XcXc and genotype of man would be XY.
The gametes would be - Xc, Xc and X, Y
then the cross:
Xc Xc
X XXc XXc
Y XcY XcY
so the offspring would be -
Carrier female = XXc (50% chance in total and 100% in daughters)
RGCB daughters = 0%
RGCB male = XcY (100% in sons and 50% of total children)

how is spark formed, and why might a spark start an explosion?
Answer:When the applied electric field exceeds the dielectric breakdown strength of the intervening medium, a spark is generated. In a mechanism known as dielectric breakdown, the exponentially increasing electrons and ions allow regions of the air in the gap to become electrically conductive.
An electrostatic spark causes the blast. The sudden rise in temperature that occurs as the mixture ignites causes a massive increase in gas pressure. The ensuing increase in pressure could collapse the chamber with a noisy explosion if the burning vapour were to be trapped.

Explanation:
JND stands for:
Select one:
a. Just noticeable theory
ob. Just noticeable direction
c. Just negotiable difference
d. Just noticeable difference
The correct answer is D. Just noticeable difference.
Explanation
In psychophysics, a barely noticeable difference, usually abbreviated with lowercase letters JND, is the smallest detectable difference between an initial and a secondary level of a particular sensory stimulus. Also known as limen difference, differential threshold, or less noticeable difference. According to the above, the correct answer is D. Just noticeable difference.

The function of some cyclin-dependent protein kinases (CDKs) has been remarkably conserved in evolution. Indeed, coding sequence for the human protein Cdc2 is able to substitute for the CDC28 gene in S. cerevisae and allow the yeast cell to grow and mate essentially normally. The following sequence near the NH2-end of the molecule is identical in both proteins: Gly-Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala. Does this mean that nucleotide sequences of the two genes coding for this region of the polypeptide are also identical
Answer:
No, because the genetic code is redundant
Explanation:
During the translation, a single amino acid may be coded for by more than one codon. It is for that reason that the genetic code is considered to be redundant. Tryptophan is the unique amino acid specified by a single codon. In this case, it is likely that silent mutations at the nucleotide sequence that encode for the Glu-Gly-Thr-Tyr-Gly-Val-Val-Tyr-Lys-Ala protein motif might have accumulated during the evolution of both CDK genes, modifying thus their nucleotide sequences while preserving the same protein sequence.
Some people's earlobes dangle or flap unattached, while others don't. This trait is genetically determined. Use the genetics simulation to explore the genes that determine whether earlobes are attached or unattached. One trait is dominant and the other is recessive. See what happens when you cross parents with different genetic combinations. Follow the specific instructions for each trial.

One species called the naked mole-rat, has some unique differences. They have a social structure similar to that of ants and bees, they are smaller in size and are mostly ectothermic. They live in harsh, dry scrub land habitats and forage mainly on underground tubers which are widely dispersed. Why you think this species evolved back to an ectothermic life style rather than staying endothermic like all other mammals
Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.

Which word describes the process by which a human transmits a disease to an animal?
Answer: reverse zoonosis or anthroponosis.
Explanation:
Answer:
a zoonosis
Explanation:
is an infectious disease caused by a pathogen (an infectious agent, such as a bacterium, virus, parasite or prion) that has jumped from an animal (usually a vertebrate) to a human. Typically, the first infected human transmits the infectious agent to at least one other human, who, in turn, infects others
this type of consistent adaptation between two species is known as
Answer:
Symbiosis or Mutualism: When two species live together in a close association that is helpful to both species, the relationship is known as symbiosis. The oxpecker bird and the rhinoceros exhibit this relationship. The oxpecker receives protection and obtains food from the ticks and other pests infesting the rhino’s skin.

Select the neurological problems that affect women more often than men.
Answer: Imma say the Parkinson's disease.
This disabling neurological disease affects about 50% more men than women.More than two times more men than women are affected by antisocial personality disorder and substance use disorder. Several cancers, including stomach cancer (2:1), oesophageal cancer (3:1), liver cancer (2:1 to 4:1) and oral cancer (2:1 to 3:1), which have mostly lifestyle-based risk factors, are more common in men.
