All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?
a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

Which model represents a DNA molecule?
Answer: The answer is D because the way they line up!!
Explanation:
The model that gives a true representation of a DNA molecule would be the 4th model.
What is the structure of DNA?According to Watson and Crick, the DNA is a double strand molecule with each strand twisting around one another to form a ladder-like, double helix structure.
Also, there is a complementarity of nucleotide bases such that Adenine (A) always pairs with Thymine (T) while Guanine (G) always pairs with Cytosine (C).
Thus, model 4 ticks all the characteristics of a typical DNA molecule.

What is Bacteria?Eukarya is not the correct answer because they have organelles and a nucleus. Archaea is not the correct answer because they have organelles and a nucleus.
Microbes known as bacteria have simpler cell structures than many other types of creatures. One DNA loop serves as their command center and houses all of their genetic data. Instead of a nucleus, some bacteria have an additional ring of genetic material called a plasmid.
Genes that offer the bacterium a competitive edge over other bacteria are frequently found in the plasmid. For instance, it might have a gene making the bacterium immune to a specific antibiotic.
Therefore, Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Ee, Hh, and Bb, that determine if gremlins are evil (E), have hair (H), and biting teeth (B). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes: 48 ee Hh bb 36 ee hh Bb 400 ee Hh Bb 4 Ee Hh Bb 426 Ee hh bb 46 Ee hh Bb 38 Ee Hh bb 2 ee hh bb What is the recombination frequency between genes E and H
Recombination frequency determines if two genes are linked or if they segregate independently from each other. The recombination frequency between E and H is 8%
What are linked genes?Linked genes are those that are too close to each other in the same chromosome and they do not segregate independently.
These are the linked genes that do not exhibit an independent distribution, and they are inherited together more frequently.
What is recombination frequency?Recombination frequency can be defined as the crossing over events frequency occurring between two genes.
The value of recombination frequency indicates weather genes are linked or not. The maximum recombination frequency is always 50%.
When RF is 50% or more, we can assume that genes are not linked.
In the exposed example, we can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent.
Parental)
400 ee Hh Bb
426 Ee hh bb
Double recombinant)
4 Ee Hh Bb
2 ee hh bb
Simple recombinant)
48 ee Hh bb
36 ee hh Bb
46 Ee hh Bb
38 Ee Hh bb
We will call Region I to the area between genes E and H and Region II to the area between genes H and B.
------------E------------H--------------B-----------
/---RI------//------RII-----/
To calculate the recombination frequency between E and H we just need to consider region I. We will call P1 to the recombination frequency in this region.
P1 = (R + DR) / N
Where:
R is the number of simple recombinants in this region, DR is the number of double recombinants in each region, and N is the total number of individuals.Now, let us analyze the information.
We know that individuals carrying double recombinant gametes are
Ee Hh Bbee hh bbWe know that the recessive parent from the testcross could only provide the following gametes ⇒ ehb
This leads us to assume that the followings are the double recombinant gametes from the trihybrid parent,
EHBehbSince these gametes are the product of a double recombination event in region I and II, we can assume that the parental gametes of the trihybrid individual are
eHbEhBHence the simple recombinant gametes in region I are
EHbehBNow, according to this analysis, we know that
Simple recombinants in region I
36 ee hh Bb
38 Ee Hh bb
Double recombinants
4 Ee Hh Bb
2 ee hh bb
Total number of individuals
N = 1000
Recombination frequency in Region I
P1 = (R + DR) / N
P1 = (38 + 36 + 4 + 2) / 1000
P1 = 80 / 1000
P1 = 0.08 = 8%
The recombination frequency between genes E and H is P1 = 8%

What was difficult about measuring the 3x5 card? Why?
Answer:
can you give me some answers
Explanation:
As with Part H. you have a total body concentration of 300 mOsM and body volume of 3 liters. You now add 2 liters of a 500 mOsM solution. The solution is equal parts NaCI (nonpenetrating) and urea (penetrating), so it has 250 mosmol/L NaCI and 250 mosmol/L urea. Answer the following questions about your new solution:
Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
The solution is_______ osmotic to the body.
What is the concentration of nonpenetrating solutes (NP) in the solution?
What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.)

300 mosmol/L
Stayed the same
300 mosmol/L
Hypo
lso
decreased
stayed the same
Answer:
- The solution is hyperosmotic to the body.
- What is the concentration of nonpenetrating solutes (NP) in the solution? 500 mosmol/L
- What is the internal concentration of the body's cells? (All intracellular solutes are nonpenetrating.) 300 mosmol/L
- When the cells reach equilibrium after addition of the solution to the body, has cell volume increased, decreased, or stayed the same? increased
- Based on your answer regarding water movement, the solution was hypotonic to the body's cells.
Explanation:
A hyperosmotic (or hypertonic) solution is a solution with a greater solute concentration. If a cell is placed in a hyperosmotic solution the water will leave the cell and the cell will shrink. Conversely, a hypotonic solution is a solution that has a lower concentration of solute. If a cell is placed in a hypotonic solution the water will enter the cell through osmosis and the cell increases in size. In this case, the NaCl is a non-penetrating solute, and thereby the concentration in the body's cells maintains constant. Moreover, urea is a penetrating solute, thereby it will penetrate in the cells until the equilibrium is reached (i.e., the cells will increase in volume).
