k. Tendon 10. The cordlike part that attaches a muscle to a bone
l. Transverse (T) tubule reticulum 1. Membranous channel extending inward from muscle fiber membrane
Explanation:
A muscle has around it epimysium, which is connective tissue. Inside the epimysium, there are fascicles, and around each of them, there is perimysium. Inside every fascicle, there are muscle fibers, each of them is surrounded by a connective tissue called endomysium. Between every muscle, there is also connective tissue and is called fascia. The connective tissue has vessels and provides support.
The muscle cells are called fibers. They have a membrane, the sarcolemma, a cytoplasm, the sarcoplasm, and a sarcomere, which is the functional unit of the fiber, in other words, it is the structure responsible for the contraction. The sarcomere has different bands made of thick filaments of myosin and thin filaments of actin. They are the light and dark striations that go from disc z to disc z when we observe the sarcomere under a special microscope. The sarcoplasmic reticulum is the place that stores the calcium necessary for the contraction of the fiber, and the transverse tubule reticulum allows the contraction of various fibers since they spread the action potential amongst fibers.

Which organism will have DNA most similar to the turtle?
Answer:
the answer is leopards!
Explanation:
I answered a similar question like this yesterday,
Hope it helps!!
The organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as turtles, which is Testudines, which is present in Option A.
What is DNA sharing among ancestors?Organisms that are closely related evolutionarily tend to have more similar DNA sequences than those that are more distantly related because they share a more recent common ancestor and have had less time to accumulate genetic differences. Turtles belong to the class Reptilia, which includes other reptiles like lizards, snakes, crocodiles, and birds. Within the reptile class, turtles are classified under the order Testudines, and other members of this order include tortoises and terrapins that share common characteristics with turtles.
Hence, the organism that will have DNA most similar to the turtle's will be other reptiles, particularly those in the same order as the turtles present in Option A.

Answer:
Tissue is a group of cells that have similar structure and that function together as a unit. primary types of body tissues include epithelial, connective, muscular and nervous tissues. Epithelial tissues form the covering of all body surfaces , ine body, cavities and hollow organs, and are the major tissues in glands.
A tissue is composed of a group of cells that are determined to play a specific function. The Cytoplasm is a dense gel-like material that is filled within the cell.
What is Cell theory?Cell theory was proposed by M. Schleiden and T. Schwann in 1838. According to them, there are three postulates of cell theory that are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms.The cell is the structural and functional unit of life.Cell theory was further refined by German biologist Rudolf Virchow in 1855. According to him, all cells are arising from pre-existing cells. The Cell wall generally protects the cell and it is most commonly found in plants, animals, bacteria, etc.
Inside the cell, there are various organelles present that perform specific functions for the survival of the cells. The nucleus is known as the brain or controlling center of the cell, which transmits genetic information from one generation to the next.

Homologous recombination occurs in a heterozygote in which alleles D and d differ by a single base pair. The D allele has a G (a GC base pair) at one position, whereas the d allele has a C (a CG base pair) at the same position. If branch migration causes heteroduplex formation across this position, what is the expected outcome
Answer:
Mismatch DNA repair mechanism recognizes the abnormal base pairing (G-G base pair) and may correct it by converting the D allele to d
Explanation:
The DNA mismatch repair can be defined as a specialized mechanism that recognizes and repairs errors in the nuclotide sequence (such as, for example, bases erroneously incorporated) during DNA replication and recombination. The DNA mismatch repair is a system that also acts to repair the DNA after damage. It has been shown that the DNA mismatch repair mechanism leads to the generation of a DNA molecule with one chain that has the nucleotide sequence arising from DNA repair and one parental chain. In this case, it is expected that the DNA mismatch repair mechanism will identify the abnormal G-G base pairing and then this system may change the D allele to a d allele by introducing a C base instead of a G base in the DNA strand.

10. What happens when environments change and species cannot adapt?
There are ongoing arguments among taxonomists as to which phyla represent the closest relatives of phylum Annelida. Some propose that these worms share a common ancestor with the arthropods (crabs, insects etc.). However, the majority continue to keep the annelids lumped together with the Lophotrochozoa. The reasons for this are many but probably the least disputed comes from:______.
a. the segmented body plan of the annelids.
b. molecular analysis.
c. metamerism.
d. schizocoelous origin of the coelom.

a. the segmented body plan of the annelids
Explanation:
lophotrochozoan is a taxonomy of animals that includes annelids, bryozoans, and brachiopods. This taxonomy of creatures was defined in 1995 as the last ancestor of the taxa of worms, mollusks, and annelids. Their classical definition depends on the topology of the spiral tree of life. Annelids have a segmented body part wherein the external morphological features are repeated in every body segment. It allows the animal to become bigger and makes their movement more fat and efficient.Answer:

Sickle cell anemia is a genetic condition that occurs because of a single point mutation in the DNA gene for hemoglobin. How is this mutation expressed in humans?
A.) The protein coded by the DNA has a different amino acid sequence
B.) The chromosome caring this gene changes shape during cell reproduction
C.) The hormones in the bladder change by increase differences in genes
D.) The carbohydrate code by the DNA has a different structure
Answer:
B.) The chromosome carrying this gene changes shape during cell reproduction
Explanation:
According to this question, Sickle cell anemia is a genetic condition that occurs when the HBB gene that codes for haemoglobin protein undergoes a point mutation. Mutation alters the genetic sequence of a gene.
This mutation expresses itself when the chromosome 11 carrying the mutated gene changes shape during cell reproduction. Normal Red Blood Cell has a disc-shaped structure, however, this mutation causes a change in shape of the chromosome involved.

Explanation:
The blue people of Troublesome Creek Kentucky were genetically isolated from the rest of the world for generations. A rare recessive allele that causes people to have a blue tone to their skin, methemoglobinemia, became disproportionately common within this population by way of their genetic isolation. In the last few decades new roads opened leading to the end of this communities isolation. To the surprise of many, the methemoglobinemia phenotype disappeared along with their genetic isolation. Which of the following may best explain the apparent disappearance of this once common trait?
a. Methemoglobinemia did not confer any physical advantage so that the trait was selected against.
b. Methemoglobinemia was probably lethal and all those that carried this trait died and did not have a chance to pass on this trait to future generations.
c. Those that had the traits simply did not have descendents.
d. With the end of genetic isolation gene flow took place.
Answer:
The correct answer would be - d. With the end of genetic isolation gene flow took place
Explanation:
It is given that people of Troublesome Creek Kentucky were isolated and have a rare recessive allele that results in a blue tone to their skin. However, later these isolated people connected with the people from outside, and due which allow them to intermate. Intermating among populations from isolated and people from outside leads to gene flow.
Methemoglobinemia was present in the isolated population as they had both recessive alleles in their genotype and other hand people from outside might have heterozygous or both dominant allele genotypes that make them free from this disorder.
Due to the intermating and gene flow, the number of heterozygous conditions rises and after many generations slowly methemoglobinemia could have disappeared due to the masked recessive allele.
