Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue bone, blood, and lymph tissues.
All body surfaces are covered in epithelial tissues, which also line bodily cavities and hollow organs and make up the majority of glandular tissue. Connective tissues are presents in the blood cells in the human body. Loose connective tissue, adipose tissue, dense fibrous connective tissue, elastic connective tissue, cartilage, osseous tissue, and blood are further more tissues in the body.

Conjugation differs from reproduction because conjugation Group of answer choices transfers DNA horizontally, to nearby cells without those cells undergoing replication. transcribes DNA to RNA. replicates DNA. transfers DNA vertically, to new cells. copies RNA to make DNA.
Answer:
it is differs from reproduction because conjunction group of answers
Conjugation transfers DNA horizontally, to nearby cells without those cells undergoing replication.
Conjugation is a mechanism of genetic transfer in bacteria where genetic material, usually in the form of plasmids, is transferred from one bacterial cell to another. Unlike reproduction, which involves the replication and inheritance of genetic material through cell division, conjugation allows bacteria to transfer genetic material horizontally between cells that are in close proximity to each other.
During conjugation, the donor bacterial cell containing the plasmid makes contact with the recipient cell through a specialized structure called a pilus. The plasmid DNA is then transferred from the donor cell to the recipient cell through this pilus. The transferred DNA can include genes that provide advantages such as antibiotic resistance or the ability to metabolize certain substances.
The key difference between conjugation and reproduction is that conjugation does not involve replication of the recipient cell's entire genome. Instead, it transfers specific genetic material from one cell to another. The recipient cell does not undergo replication as a result of conjugation but acquires new genetic information from the donor cell.
Reproduction, on the other hand, involves the replication and inheritance of the complete set of genetic material in the parent cell. It results in the production of offspring cells that are genetically identical or similar to the parent cell.
In summary, conjugation is a form of genetic transfer in bacteria where DNA is horizontally transferred between cells without those cells undergoing replication. It allows for the exchange of genetic material and the acquisition of new traits by recipient cells. Reproduction, on the other hand, involves the replication and inheritance of genetic material through cell division.

What happens during S phase?
O A. Chromosomes are duplicated.
O B. DNA separates into two nuclei.
O C. The cell splits in two.
O D. Cytoplasm is manufactured.
Answer: A. Chromosomes are duplicated.
Explanation: This is the correct answer on the quiz.
Chromosomes are duplicated in S phase. Therefore, option (A) is correct.
What do you mean by S phase?
Between G1 phase and G2 phase, DNA replication takes place during S phase of the cell cycle. The processes that take place during S-phase are tightly controlled and highly conserved.
The cell replicates its genetic material entirely during the S phase of DNA synthesis; At the end of S phase, a normal diploid somatic cell with a DNA complement of 2N acquires a DNA complement of 4N.
DNA synthesis or replication occurs during the S phase of the cell cycle, which occurs prior to the interphase. Before entering mitosis or meiosis, the cell's genetic material is replicated in this manner, leaving enough DNA for daughter cells to divide.

Suppose you traveled back in time and located the first animals to have evolved feathers. You found that these animals were tree-dwelling ectotherms, able to run quickly but unable to fly. You also noticed that only males had feathers. Which hypothesis of feather evolution would these data most support? Feathers initially evolved in a role associated with ________.
Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.

I'm a bit stuck and need some help. Much appreciated!
Think recessive phenotypes as paper and dominant phenotypes as teared paper. Once paper is teared, it can't be fixed. Not even tape. It'll just leave that mess exposed. Same with dominant phenotypes. It just takes one dominant trait to change the looks of future offspring.
If you don't tear the paper, everything is fine. Same with recessive phenotypes. As long as there's no contact with any dominant phenotypes, the looks of future offspring will change.

They are different species.
O They live in the same location.
O They eat different foods.
O They have a wide range of variation
Finches have adapted different beak sizes and shapes because they eat different foods. So the correct option is C.
What is natural selection?Natural selection is a mechanism for evolution to happen. It is the process by which living organisms acquire certain characters according to their needs.
It is important to understand natural selection to understand the essential concepts of the processes by which living organisms have been able to develop the complex structures which are helped them to survive.
Natural selection results from various conditions of environment, ecosystem and heredity. An example of natural selection is the development of antimicrobial resistance to pathogens.
Finches are known to have developed different sizes and shapes of beaks according to the kind of food that they eat. If they fed on insects, they had long and pointed beaks. If they fed on seeds and nuts, they had broad and blunt beaks.
Therefore the correct option is B.

A pseudogene is a Group of answer choices second copy of a gene that functions when the original copy becomes damaged. gene that is unrelated in sequence to another gene but has the same function. gene that evolved by gene duplication and the acquisition of mutations to yield a gene product that has a slightly different function from that of the original gene product. gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Answer: Gene that arose through gene duplication, but by acquiring mutations became nonfunctional.
Explanation:
A gene is a functional unit of heredity formed by DNA. They possess a sequence of nitrogenous bases that during translation is read by ribosomes to produce molecules called proteins. A pseudogene is a DNA sequence that resembles a gene, but which has been inactivated in the course of evolution by mutations in its sequence. Thus, it is a gene that derives from other known genes and whose functions are different, may have lost their functionality or have radically changed it. To this day, it is not known exactly how pseudogenes are created, however some theories are as follows:
1. A gene duplication can generate two copies of a gene when only one is needed. A mutation would then occur that deactivates one of the copies. In addition, the duplication event may not be complete, so that the copy has incomplete promoters.
2. They may be fragments of the messenger RNA transcript of a gene may be spontaneously reverse transcribed and inserted into the chromosomal DNA. They lack the promoters of normal genes, so they are not expressed normally.
3. A gene may become non-functional or inactivated if such a mutation becomes fixed in the population. This can occur by normal means such as natural selection or genetic drift.
