Answer:
The mouth covered by chitin and intracellular granules of chitin (i.e. spindles) in nudibranchs
Explanation:
Nudibranchs are marine gastropod molluscs (Opisthobranchia, Mollusca). These organisms are carnivorous, so they feed on sponges, coral, anemones, hydroids, fish eggs, etc. On the other hand, cnidarians have specialized cells called cnidoblasts or cnidocytes that contain nematocysts made up of toxins that serve as a defense mechanism. Nematocysts are found in many species of Cnidarians such as, for example, in the tentacles of sea anemones. Interestingly, nudibranchs have developed some adaptations for feeding on these species. In the first place, nudibranchs have the mouth covered by a substance named chitin that allows them to chomp and swallow anemone tentacles. Second, they (nudibranchs) also have intracellular granules of chitin (i.e. spindles) in the digestive system that function as biological sandbags which maintain nematocyst toxins away from sensitive body parts.
The mucus coat of clownfish protects the fish from sea anemone's sting which is an adaptation clownfish developed.
What is Nematocysts?Nematocysts are cells found in which is use for locomotion and for defence and capturing prey.
Nematocysts contain coiled threadswhich is like hairlike projections called which are sensitive to touch and can penetrate the body ofprey.that may bear barbs. Nematocysts is found in Sea anemone, Hydra and so on and it is use to capture prey.The clown fish have mucus coat which prevents nematocysts from penetrating through it and hence ensures it's defence from been attacked or captured as prey by Sea anemone.Therefore, The mucus coat of clownfish protects the fish from sea anemone's sting which is an adaptation clownfish developed

What is the procedure of formation of Clastic sedimentary rocks?
Clastic sedimentary rocks are formed by the weathering process, In this process rocks get breakdown into sand, clay particles by the wind, water, and ice.
Clastic sedimentary rocks are also known as sandstone, and they are made of rocks and minerals. They are classified based upon composition, size, and texture.
Breccia is a clastic sedimentary rock with angular particles. Breccia is composed of particles that have diameter of greater than two millimeters. Breccia is formed by accumulation of angular broken rock or mineral debris. Breccia differ in composition according to the composition of mineral and rock from which the angular fragments were formed.

Retro means backwards. What is “retro” about retroviruses?
Answer:
The term "retro" in retrovirus refers to this reversal of the usual direction of transcription.
Explanation:
Retroviruses are the viruses from the virus family known as retroviridae. These are the viruses that use RNA as their genetic material and use an enzyme reverse transcriptase which is essential for their life cycle.
they called retro as they use the reverse process of the usual direction of transcription which means from RNA to DNA by duplicated their genetic material to produce DNA and incorporated into the genome of the host.

Answer:
For the first box (top left one), it is AA
For the second box (top right one), it is Aa
For the third one (bottom left one), it is aA
For the fourth one (bottom right one), it is aa
This one above ^^^ is the top line of the punnet square (the small line)
A = free-hanging earlobes
a = attached earlobes
For the first box (top left one), it is free-hanging earlobes (both "A"s are dominants, and the dominant is greater than the recessive one).
For the second box (top right one), it is free-hanging earlobes (there is at least one dominant A so it will be greater than the other "a" although there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the third one (bottom left one), it is free-hanging earlobes (again, there is at least one dominant A so it will be greater than the other "a" even though, there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the fourth one (bottom right one), it is attached earlobes (both "a"s are recessive, there is not one dominant "a" which means that it will be an attached earlobe".
This one above is ^^^ is for the second line in the punnet square (the longest line) P.S you dont have to write the explanation you can just write if it's an attached earlobe or a free-hanging one
The ratio will be 75% to 25%. The 75% will be the offsprings inheriting the free-hanging earlobes, and the 25% will be the offsprings inheriting the attached earlobe. It is most likely that the offspring will inherit the trait for free-hanging earlobe since it is the dominant allele there is.

What is one trait that could be used to separate these albatrosses into two groups of two birds each?
The correct answer to this open question is the following.
You did not attach the options for this question. However, we can answer the following.
Although there are no pictures of the Albatross, we can say that one trait that could be used to separate these albatrosses into two groups of two birds each is "a large group of solid black feathers vs. black and grey patterned feathers."
If someone ask you what are the birds with larger wings, you probably would answer "the Bald Eagle," Or any other kind of eagle. Maybe the Southamerican Condor. And those answers are incorrect. The correct answer: the Albatross.
This is a carnivore bird which wingspan varies from 6.5 to 11 to 11 feet, Its average weight is 22 pounds. These impressive birds can use their long wings to fly over the seas for miles and miles, without taking a rest.

direction of gravitational
pull of the Sun on the planet
the planet’s resultant
orbital path
direction of the planet's
velocity and momentum
Answer:
direction of gravitational pull of the Sun on the planet
Explanation:
A planet orbiting or revolving around the sun due to gravitational force of the Sun on the planet which attracts the planet and compel the planets to move in a circular path. If this force of gravity is not applied on the planets, the planets will move in a straight line instead of circular direction so gravitational pull of the Sun on the planet is very necessary for moving planets in a circular path.

In each drawing, there are lines between each atom and each molecule. What do you think the lines between atoms represent? The lines between molecules?
Answer:
Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.
Explanation:
Answer:Each straight line segment represents a bond, the ends and intersections of the lines are carbon atoms, and the correct number of hydrogens is calculated from the tetravalency of carbon. Non-bonding valence shell electrons are omitted in these formulas.Each line represents a single covalent bond (two shared electrons), so double lines represent a double covalent bond (four shared electrons). Covalent bonds are usually found in atoms that have at least two, and usually less than seven, electrons in their outermost energy shell, but this is NOT a hard and fast rule.

Which quantities define momentum?
A. Mass and speed
B. Mass and velocity
C. Mass and acceleration
D. Mass and force
The quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.
What is Momentum?Momentum may be defined as a type of physical property that remarkably describes the motion of any moving object. It is a type of vector quantity as it possesses both magnitude and direction. It may be generally characterized as the product of mass and velocity.
According to the context of this question, the momentum of any object may be calculated as follows:
Momentum, P = M × V, where M = mass of an object and v = velocity of an object.The unit of momentum is Newton-second (N-s) or kg m/s.
Therefore, the quantities that significantly define the momentum are known as Mass and velocity. Thus, the correct option for this question is B.
