Answer:
A. it is photosynthetic
Explanation:
A. it is photosynthetic - this is true - chlorophyll is a photosynthetic pigment that traps light energy to power food production. It present in green plants
B. it contains vascular tissues - this is false - eubacteria are single celled organisms that do not form tissues
C. it contains mitochondria - this is false - prokaryotic cells do not contain membrane-bound organelles like mitochondria
D. it is heterotrophic - this is false, plants and many bacteria are not heterotrophic, which means they consume other organisms for their food supply rather than creating their own (autotrophic)

When a cell gains water, what will happen to its size and mass?
Answer:
The cell will swell up and eventually burst.
Explanation:
Cells swell if there’s more salt in a cell than outside it, the water will move through the cell membrane into the cell, causing it to increase in size. if too much water gets in, the cell will burst.

Which were likely the closest ancestors to early animals?
a Mosses
b Cyanobacteria
C Colonial protists
d Algae
Answer:
Algae i believe
Explanation:
I say this because the earliest animal is comb jelly
Most likely the closest ancestors to early animals are colonial protists. This is because they are eukaryotic, multicellular organisms that have mitochondria.
What do you mean by Ancestors?Ancestors may be defined as an early type of animal or plant from which others have evolved.
Due to living in groups, they are known as Colonial protists. The most primitive organisms are cyanobacteria which are single-celled organisms.
Therefore, most likely the closest ancestors to early animals are colonial protists.

What is a rule for making a neutral atom which has no charge?
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

What type of data is recorded by the electrocardiogram?
OA.
the amount of oxygen in the blood

the electrical activity of the heart
OC. the sound of the heart beating
OD
the force from the heart beating
20 Edmentum. All rights reserved.
Answer:
The type of data that is recorded by electrocardiogram is the electrical activity of the heart.
Explanation:
The heart functions through a nerve structure —the sinus node, the atrioventricular node and the His-Purkinje system— which determine the functioning of the organ through electrical activity.
The electrocardiogram, or EKG, is a device that records the electrical activity of the heart. This allows us to know any alteration in said activity, such as arrhythmias, interruption of electrical impulses or alteration of the heart's anatomy.
In order for the EKG to be able to record the electrical activity, electrodes must be placed on the limbs and chest, which are the sensors in charge of receiving the information of the heart's electrical activity.
Other options are not correct because:
The amount of oxygen in the blood is measured by using oximeters or blood gas measurement. The sound or the force from the heart beating can be recorded by auscultation with a stethoscope.Which of the following is NOT a necessary characteristic of a living things?
Answer:
B) Living things eat.
Explanation:
Not all living things have to eat. Living things, like plants, make their own food.
The following is not a necessary characteristic of a living thing: that they eat, which is present in option b, as the living organism grows, reproduces, and is made up of cells.
What is the significance of the living organisms?Living organisms are made up of cells, and there are many forms of living organisms, such as prokaryotic bacteria and complex multicellular animals, and all of them grow and reproduce. Living organisms such as plants don't eat like animals, but they do take part in the reproduction process to form new plants, and the living forms grow in size as they develop.
Hence, the following is not a necessary characteristic of a living thing: that they eat, which is present in option b, as the living organism grows, reproduces, and is made up of cells.

Whats the difference between bacteria cells, and blood cells?
Answer:
recent study out of the Weizmann Institute in Israel states that the number of bacteria may actually be very similar to the number of human cells in the body.
While this results in about 1.3 bacterial cell per human cell, the numbers may vary significantly from person to person and could change significantly with each defecation. They estimate that the range of bacterial cells goes from about 30 to 50 trillion in each individual. Women may also have a higher ratio of bacterial cells than human cells because they have fewer human cells, specifically red blood cells.

Homologous chromosomes are chromosomes that are the same? true or false
Answer:
False
Explanation:
The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must do, especially the actual experiment part. You must also list the "controlled variables", the "independent variable", and the "dependent variable
Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.
Explanation:
We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.
Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:
1. We can apply Vitamin C in a form of solution on the ashy skin.
2. Observe the changes on the skin directly and apply for 2-3 times in a day.
3. Observe the changes on the skin after a week.

A student states that exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time. An experiment is carried out to test this hypothesis. One group of ten students sits quietly before squeezing a clothespin as many times as possible during a one-minute interval. A second group of ten students does 25 jumping jacks before squeezing a clothespin as many times as possible during a one-minute interval. What is the independent variable?
Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
