A
Explanation:
Mitosis vs Meiosis, someone help me with this, ill give brainiest.
Mitosis gives two nuclei, and hence two cells while meiosis gives four.
2. CellsMitosis gives identical cells to each other and to the mother cell while meiosis leads to genetic variation due to crossing over and independent assortment.
3.DivisionMitosis includes one division while meiosis includes two.
4. Crossing overIt takes place in Meiosis while absence in Mitosis.
5. ChromosomesMitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes)

2. What can you infer from the fact that ants make up
20 percent of the mass of all land animals combined?
a. Ants are very heavy
b. Ants live for a long time
c. Ants thrive in locations all over the world
d. Ants breed faster than any other organism on earth
Ant breed faster than any other organism on earth, 20% of earth mass have land animals. Many ants are on the earth. Thus, option D is correct.
What are the major features of ants ?Ants belongs to Formicide family which is related to so called eusocial insects like bees and termites. It is appeared in the Cretaceous period that is more than 90 million years ago.
The diversity of ants is every where except Antarctica.
The body has three parts such as a head, a meso-some and metasoma or gaster.
Ants are mostly omnivorous but can be scavengers , predators or herbivores based on ecological context.
The reproduction in which young, queens fly during mating time, fertilize with male, this flight is called as nuptial flight.
Then queen lay eggs, then larvae emerge to become pupae, then adults such as workers, soldiers, males or other queens are produced.
Thus, option D is correct.

Which of the following IS
an example of reproductive isolation?
O two populations
of finches that cannot produce viable offspring
O two populations of finches that have different feather colors
• two populations of salamanders that live in different lakes
O two populations of salamanders that
have different tail lengths
An example of reproductive isolation is two populations of salamanders that live in different lakes. Thus, the correct option is C.
What is Reproductive isolation?Reproductive isolation may be defined as the inability of a species to interbreed successfully with related species members due to isolating mechanisms.
Reproductive isolation may leads to speciation. A single specie scan generates multiple species via reproductive isolation. The members of the same species undergo reproductive isolation due to several isolating mechanisms.
The isolating mechanisms include geographical, behavioral, physiological, or genetic barriers.
Therefore, the correct option for this question is C.

Where can the process of lactic-acid fermentation be found
Answer:
Lactic fermentation is a minor process which occurs after glycolysis in anaerobic respiration.
Explanation:
In it, an enzyme found in most every organism called lactate dehydrogenase catalyzes a reaction between the NADH produced from glycolysis with the pyruvate molecules to create the NAD+ necessary to begin glycolysis

*EXTRA PTS* How much weight is needed for a 10 m high ball to achieve 400 J of potential energy?
Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
3. Yes - At maximum stretch the ball stops. The ball is now 2 meters plus x below the starting point where x is the stretch distance down. The total energy is all potential in the springs and gravitational and is m g (2 + x)

4. What is an example of positive feedback?
a. Regulating blood glucose levels
b. Maintaining internal body temperature
c. Producing milk in nursing mothers
Answer:
C
Explanation:
It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

What characteristic do sea stars and brittle stars have in common?
Both have flexible joints.
Both have teeth-like feeding structures.
Both use tube feet to catch prey.
Both have tentacles.
Answer:
They typically have a tough, spiny surface, which inspired their name (in Greek, echinos means “spiny” and derma means “skin”). They also have the unusual ability to regrow lost body parts, and sea stars and brittle stars can regrow arms if broken off or eaten
Explanation:
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
What are sea stars and brittle stars?Echinoderms with a star form that belongs to the class Asteroidea are known as starfish or sea stars. These terms are frequently used incorrectly to refer to ophiuroids, which are properly called brittle stars or basket stars in common usage. Due to their membership in the class Asteroidea, starfish are also referred to as asteroids.
The benthic (bottom-feeding) fauna of the maritime environment includes brittle stars. They belong to the Phylum Echinodermata, which includes marine organisms with radial symmetry, five components, and frequent spines. They are commonly referred to as echinoderms.
Sea stars and brittle stars both use tube feet to catch prey. Therefore, option C is correct.
