Which genus of single-celled organisms feeds by surrounding its food
with cytoplasm and engulfing it?
Answers
Answer:Amobea
Explanation:
The single-celled organism that feeds its food from the surrounding by engulfing is Amoeba. Amoeba is unicellular organism, generally found in freshwater pools, lakes, and in aquatic vegetation.
Amoeba is a unicellular organism belonging to the group of protozoa. It reproduces through binary fission. The amoeba has the ability to change its shape, which helps the organism to obtain food from the surrounding. Amoeba protrudes the cytoplasm by making a finger-like projections, known as pseudopodia. The pseudopodia engulfs the surrounding food particle by making a food vacuole. This process of engulfing food is known as phagocytosis.
Therefore, the amoeba uses phagocytosis to engulf food particle.

Suppose a scientist is doing an experiment to determine the effect of an all-organic diet on the occurrence of
cancer in rats. Which of the following would be the best control group for this experiment?
A. Rats fed a standard rat diet (not organic)
B. Rats fed an all-organic diet
C. Pats fed an all-organic diet, but half the amount of normal
D. Rats that are not fed anything
Answers
Hmm... I'm not 100% sure but I'd say it was D.
Rats fed a standard rat diet (not organic) will be the best control group for this experiment. The correct option is A.
What is control group?A control group in a scientific experiment is a group that is isolated from the rest of the laboratory activity and where the regression analysis being evaluated cannot influence the outcomes.
This isolates the independent variable's effects on the experiment and can help rule out other explanations for the experimental results.
An experimental group is made up of participants who have their independent variable manipulated in some way. These are the people who receive special treatment.
The best control group for this experiment will be rats fed a standard rat diet (not organic).
Thus, the correct option is A.

mass.
Why is this statement true?
O Hydrogen is a gas, but oxygen is a solid.
O Hydrogen atoms have a lower mass than oxygen atoms.
• Hydrogen atoms make up more of water's mass than oxygen atoms.
Hydrogen is present as single atoms and oxygen is bonded in compounds,
Answers
Answer:
Hydrogen atoms have a lower mass than oxygen atoms.
Explanation:
The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.
What is hydrogen?
Hydrogen is the most abundanet element representing nearly three quarters of the mass of the universe. Hydrogen is found in the water that covers 70% of the surface of our planet as well as in all organic matter. Hydrogen is the simplest element in the universe. It is composed only of one proton (p) and only one electron (e-).
Hydrogen is the lightest element of all elements and gases; it is 14 times lighter than air. A "spill" of hydrogen gas immediately diffuses into the air and pollutes neither the ground nor the water table. Hydrogen is invisible, odorless and nontoxic. It does not cause acid rain, does not deplete the ozone layer and does not generate dangerous emissions.
Carbon is so abundant in living things even though oxygen is the most abundant element on Earth because carbon atoms can bond with one another to make chains and cyclic structures whereas oxygen atoms cannot form chains or cyclic structures.
Therefore, The statement which is true is Hydrogen atoms have a lower mass than oxygen atoms. Thus, option C is correct.

Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answers
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes

Answers
Answer:
B. generating more nerve cells
Explanation:
Mitosis is the process whereby a cell divides into two genetically identical daughter cells. It is way through which living cells reproduce and multiply themselves.
Hence, a nerve cell that do not typically undergo mitosis will be incapable of replicating/multiplying itself, hence, unable to generate more nerve cells.

Answers
Answer:
hygrometer measures humidity
barometer measures air pressure
wind sock measures wind speed and Direction
anemometer measures wind speed
The terms with their respective measurable device can be matched as:
1. Hygrometer is a type of device used to measure the content of water vapor or moisture in air or soil.
2. Barometer is a scientific instrument that is used for the measurement of air pressure. Temperature, wind patterns, and the earth's rotation affect the air pressure.
3. Windsock is a type of conical tube that is used to understand the direction of the wind. Windsocks are easily observed at airports and beaches.
4. Anemometer is a type of device, which consists of three spherical plates. The plates are used to measure the speed of the wind.

Answer:
Natural Selection (Answer Below)
Explanation:
Natural Selection is the selection of a more beneficial trait. For example, if trees get covered in soot all the white beetles and butterflys are going to stand out like a sore thumb, but the beetles and butterflies that adapted and evolved now have better traits that help them hide predators. The predators have a harder time finding the now black colored butterflies and beetles due to the black soot meaning the beetles and butterflies will have a higher survivability
