function is called
A a cell
B an organism
Ca system
D a tissue
Answer:
I believe its a system.
The circulatory system is an organ system in the body that helps maintain
homeostasis by transporting oxygen, nutrients, and other substances throughout
the body and removes wastes from tissues. The circulatory system includes the
heart, blood vessels, and blood.

Based on the information in the table, which types of cells are present in tissues
that comprise the circulatory system? Select all that apply.
a. Fat cells are part of the circulatory system because they store energy for the
system.
b. Beta cells are part of the circulatory system because they are found in the
pancreas and secrete insulin, which keeps blood glucose level in response to
food intake.
c. Hair cells are part of the circulatory system because they are found in the ear
and transfer vibrations to neural signals that are interpreted by the brain as
sound.
d. Cardiomyocytes are part of the circulatory system because they are muscle
cells found in the heart, which pumps blood throughout the body.
Thank you!
Based on the information in the table, the types of cells present in tissues are Cardiomyocytes are part of the circulatory system because they are muscle cells found in the heart, which pump blood throughout the body. The correct option is d.
What are cardiomyocytes?The cell that contracts the heart is called a cardiomyocyte, and it does so with the help of a complex network of ion transporters and contractile proteins with the aim of efficiently carrying out the contraction-relaxation cycle.
Typically, pacemaker cells, force-producing ventricular and atrial CM, and cardiomyocytes (CM) are separated.
Therefore, the correct option is d. Cardiomyocytes are part of the circulatory system because they are muscle cells found in the heart, which pump blood throughout the body.

1. Summarize the steps of the scientific method.What is the purpose of the control in an experiment? The variable?
Answer:
You make an observation, ask a question, form a hypothesis, make a prediction about the hypothesis, test the prediction and lastly use the results to make new hypotheses or predictions.
This increases the reliability of the results (A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable)
The things that are changing in an experiment are called variables. A variable is any factor, trait, or condition that can exist in differing amounts or types.

By which mechanism does older oceanic rock move at a ridge? Magnetic forces move the rock. Continents drift and move the rock. The ridge subducts and moves the rock. New molten material rises and moves the rock.
Answer:
it is d the answer is right our welcome
Explanation:
The mechanism by which older oceanic rock move at a ridge is : ( D ) New molten material rises and moves the rock
Oceanic rocks ( crust ) are made up of basalt and gabbro. Oceanic crust is thinner when compared to continental crust because of the continental crust are composed of andesite and granite which are light colored as well.
Older Oceanic rocks are moved at the ridges only when new molten materials are formed and these material rises from the crust causing the older Oceanic rocks to move.
Hence we can conclude that the mechanism by which older oceanic rock move at a ridge is New molten material rises and moves the rock.

What will happen to the rate of photosynthesis, if the temperature is
either above or below the optimal range?
it will increase
it will decrease
it will remain unchanged
Plz answer this fast!
Answer: im not 100% but i think its it will increase
Explanation:
At temperatures above 68 degrees Fahrenheit,or 20 degrees Celsius,the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.

They need to be taken outdoors for excretion, and walk.
The mating period is not fix and not easily done.
The four like fishes like turtle and squid are difficult to be handled in aquarium.
The four legged fishes do not come in fishing net during aquarium cleaning.
There are chances of being biten by four legged animals and their associated diseases like rabies.
These animals can lick the food we eat and contaminate the food.
The animal feces may produce air pollution.

What is the role of light and chlorophyll in photosynthesis?
Explanation:
During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
In photosynthesis, role of light is to convert water and carbon dioxide to organic products and chlorophyll helps in absorbing light energy from the sun.
What is photosynthesis?It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Homologous chromosomes may exchange segments, this is called crossing over. Crossing over increases genetic
variability
Where would you add crossing over" to the Venn diagram?
Answer: Meiosis
Explanation:
Crossing over of a chromosome always happen in meiosis 1. The material between the different sister chromatid in exchanged, so each gamete will be different of each other.
According to the question, the correct option is meiosis.
What is crossing over?Crossing over is the exchanging of genetic material that occurs in the germline. During the formation of egg and sperm cells, also understood as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
Thus, meiosis is correct.
