Tissue is a term that best describes a group of similar cells working together.
What is a tissue?
First, cells on their own can function individually, they are the basic unit/ building block of every living organism, and they have the ability to grow, multiply and die. The cells in a Kangaroo provide structure for the body.
But, when two or more cells come together to perform a similar function, then they become a tissue. Tissue comprises of similar cells that work together to perform a specific task.
From the passage, connective tissue is formed from muscle cells of a kangaroo that organize together to form the structures that let a kangaroo walk, run, and hop, allowing it to avoid predators.
In summary, group of similar cells form tissues so they could perform a specific function.

True or false: ATP synthase converts ADP into sugars
*if false, state what it really converts into
It is a false statement that ATP synthase converts ADP into sugars. It converts ADP to ATP.
What is ATP synthase?The ATP synthase is an enzyme that is responsible for the production of ATP from ADP. The term ATP is adenosine triphosphate while the term ADP is adenosine diphosphate.
We know that the enzyme ATP synthase is a precursor, in the presence of the precursor, there is the conversion of the ADP into ATP which is the energy molecule of the living cells.

In a feedback loop the specific variables that is changing and that the body is regulating is called the?
The stimulus or physiological variables is the item to be regulated, the maintenance of the feedback loops for the body regulation is called homeostasis (internal activity balance) that is a process that controls the stimulus to each function and how they triggers the response from the body activity. Receptors detects the changes in stimulus and Integrators compare the variable in relation to a set point to singnal the effectors to generate a physiological response.
Somo of the most showed examples of the homeostasis and the feedback loops are:
-Control of body temperature;
-Control of blood glucose.
Resume:
-The name of the process that controls the balance of the physiological variables of the body is: Homeostasis;
-The responsible to start a feedback loop is: the Stimulus (positive or negative);
-The stages for a feedback are: Stimulus ---> Receptors ----> Integrators -----> effectors;
Therefore, for this process the variable that changes in a feedback loop is the stimulus.

In an ecosystem with four levels—producers, primary consumers, and two higher-level consumers—describe where the decomposers operate within the context of these trophic levels. Provide at least two examples.What trophic levels do decomposers act on? What are examples of how decomposers act on two different trophic levels?
The Decomposers which decompose the organic matter from dead plants and animals occupy the last trophic level or the top of the ecological pyramid, the most common examples of decomposers are microorganisms like bacteria, and fungi.
For example, plants that can make their food through the process of photosynthesis are called producers, consumers are of three types herbivores carnivores, omnivores based on their consumption, and decomposers are classified by the type of organic matter they break down.
Scavengers, Detritivores, Saprotrophs.
Would the DNA of Corynebacteriumtuberculostearicum and Acinetobacter baumanniidetected by polymerase chain reaction make aneasily recognized antigen?
No, DNA won't make an easily recognized antigen because the basic structure of DNA is similar to all microbes, so DNA won't be enough to specifically recognize these two microbes.
An antigen in immunology is a molecule, molecular structure, foreign particle, pollen grain, or other foreign substance that may attach to a particular antibody or T-cell receptor. Antigens present in the body might cause an immunological reaction. The word "antigen" originally referred to something that produces antibodies. Proteins, peptides (chains of amino acids), polysaccharides (chains of monosaccharides/simple sugars), lipids, and nucleic acids can all be considered antigens.
Antibodies and T-cell receptors are examples of antigen receptors that can identify an antigen. Immune system cells produce a variety of antigen receptors, giving each cell a specificity for a single antigen. Only lymphocytes that are able to detect an antigen are activated and enlarged after being exposed to it, a process known as clonal selection.

It's needed to consider that we have two kinds of cells: somatic cells (which have 2 chromosomes inherited from our parents; 2n), and sexual cells (which have only one chromosome, inherited only from one of our parents; n). This is crucial to understand that somatic cells, whose genetic information we do not inherit, and sexual cells, whose genetic information we do inherit, differ in how they divide themselves. The first one, although they divide themselves, they can't pass a mutation to the offspring, while sexual cells can do, or the B option, which states "cells that are produced when the mutant cell divides".

- Biotic factors are living organisms that take part in an environment, for example, plants and animals are biotic factors.
- Abiotic factors are all non-living parts of an environment, for example, the temperature, the soil, the sunlight, etc.
The shell is the part of a living organism, so it can be classified as a biotic factor.
A reptile is an animal member of the class Reptilia, they can be classified as biotic factors.
The sea turtle is a living organism, so it can be classified as a biotic factor.
The temperature is a non-living part of the environment, it can be classified as an abiotic factor.
The substrate is the base where living organisms live, for example, the bottom of the marine habitats formed by rocks, sand, or gravel), it can be classified as an abiotic factor.
Detritivores are organisms that feed on dead organisms and decomposed matter, they can be classified as biotic organisms.
