Answer:A maternal x linked genes
Explanation:
In marsupials, X inactivation occurs exclusively to the paternally derived chromosome. The genes which are always expressed in this situation is that of maternal X linked genes (option A).
The gene that will be expressed in the situation is maternal X-linked genes. The correct option is A.
What is maternal gene?Maternal genes are those whose RNA or protein products are produced or deposited in the oocyte or are present in the fertilized egg or embryo before zygotic gene expression begins.
The phenotype of the offspring is determined by the maternal genotype. Maternal effects are frequently observed because the mother provides a specific mRNA or protein to the oocyte, and thus the maternal genome determines whether the molecule is functional.
X inactivation occurs only on the paternally derived chromosome in marsupials. Maternal X linked genes are the only ones that are always expressed in this situation.
Thus, the correct option is A.

3. Glucose dissolves in water because it BLANK
Select one:
O A. ionizes
O B. is a polysaccharide.
O C. is polar
O D. is nonpolar
Answer:
C
Explanation:
glucose is polar, meaning that there is a separation of charge present in the observed molecule
water is also polar as it contains electronegative oxygen, which pulls electrons towards itself, forming a dipole of partial positive (H) and partial negative charge (O)
a simple rule of thumb is "like dissolves like"
Glucose dissolves in water because it is polar. Therefore option C is correct.
Glucose, a simple sugar, and a monosaccharide is a polar molecule, meaning it has a slight positive charge on one end and a slight negative charge on the other due to its asymmetrical arrangement of atoms.
Water molecules are also polar, with a positive end (hydrogen) and a negative end (oxygen). Like dissolves like, so the polar nature of glucose allows it to interact with water molecules through hydrogen bonding, effectively surrounding and stabilizing glucose molecules in solution.
This enables glucose to dissolve in water, forming a homogeneous mixture and allowing it to be transported and utilized within living organisms for energy production and other essential processes.
Therefore option C is polar is correct.

David is playing football when he suffers from a ruptured calcaneal tendon. The rupture is accompanied by abrupt pain and the calf muscle bulges due to the release of two muscles from their insertion. Name these two muscles.
Answer:
The correct answer is - The gastrocnemius and soleus muscles.
Explanation:
Achilles tendon or calcaneal tendon is a tendon that is inserted the gastrocnemius and soleus muscles in to heels and connects it to the calf muscles. This is a strong tendon present at lower end of calf. The insertion is takes place into the calcaneus.
The gastrocnemius and soleus muscles togeter makes a strong band of tissue, back of the leg. Achilles tendinitis is characterized as the ruptured calf muscles from the insertion due to intense exercise or running fast.
The two muscles which bulged in the calf are referred to as gastrocnemius
and the soleus.
These muscles are found in the heel and are attached to the achilles
tendon in the calf of the leg. The muscles assist in movement such as
running, walking and flexion of the legs.
In this scenario, we were told that the rupture occurred in the calf and
accompanied pain was as a result of two muscles in the calf bulging which
will most likely be the gastrocnemius and the soleus muscles.

Explanation:
If the starting population of the prey is higher than the predators, the carrying capacity of the seals will be _________ than the carrying capacity of the whales.
Answer:
Explanation:
Lower
If the starting population of the prey is higher than the predator's, then the carrying capacity of the seal will be lower than the carrying capacity of the whale in future.
What is carrying capacity?Carrying capacity means the capacity of the ecosystem to provide the resources necessary for the survival of a particular species. It is different for different animals. Large animals have less carrying capacity than small animals.
In the given statement, it is given that initially the prey population was higher than the predator population. The whale is the predator of the seals. So the number of seals was higher initially. It would be advantageous for the whale.
Whales feed on the prey, and after a certain time, the prey population will decline and the whale population will increase. Initially, the carrying capacity of seals was high, but as the whale population increases, after some time the seal population will decline. In the future, the population of whales will increase more than that of seals. The carrying capacity of the seal will fall in the future.
Hence, the carrying capacity of the seal will fall in the future, but initially it was high.

During the process of DNA replication, a complementary DNA strand is formed. If the original strand of DNA is 5' ATA GTG CCC AAC GGT 3', which of the
following would be the correct complementary DNA strand?
Answer:
This question lacks options, the options are as follows:
A. 3’ ATA GTG CCC AAC GGT 5’
B. 3’ TAT CAA GGG TTG CCA 5’
C. 3’ TAT CAC GGG TTG CCA 5’
D. 3’ TAT CAC GGG TTG CCT 5’
The answer is C
Explanation:
DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’
Why is evolution considered to be a scientific THEORY?
Answer: Evolution is considered to be a scientific theory because evolution is not proven true of false, although it is widely recognized as true. A theory is defined as "a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained", meaning that it is the compliation of a certain ideas in hopes of proving something as true. The theory of evolution is the use of facts to try to explain how species have evolved over time. We have been unable to prove evolution as it occurs in front of us, but we can use evidence to support this theory.

DNA is composed of four nucleotides what are they?
Answer:
DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C)
Explanation:
When does the process shown occur in the
cell cycle?
Answer:
S- phase replication.
Explanation:
Genetic material present within DNA molecules regulates cell growth, proliferation, and cell repair. The long-chain helical macromolecules of these deoxyribonucleic acids are formed from complex sequences called nucleotides; these four monomers are joined by strong covalent bonds (adenine, cytosine, guanine, thymine).
DNA coding regions are called genes-they hold the cell's basic instructions. Multiple nucleotides and even several chromosomes may contain genes. Typically, gene expression entails transcription into RNA, and translation into amino acids/ proteins. In the S phase of the cell cycle, DNA is copied by polymerases. Here, the chromosomes are unwound and DNA is copied during replication to produce identical strands.
