His experiments showed that the inheritance of certain traits in pea plants follows particular patterns, subsequently becoming the foundation of modern genetics and leading to the study of heredity.
Answer:
he bred pea plants
Explanation:
Mendel bred pea plants and discovered that there are multiple alleles for every gene. some are dominant and others are recessive.
What is an adaptation another species have developed to resist the toxic sting of a nematocyst?
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

I have a question.... my teacher today in biology said " you think you are moving your hand by yourself, but it's actually your brain sending commands to your muscles so they can move." So I wondered.. is my brain sending commands so I can think, or am I thinking whenever I have a desire to? (Not a trick question; My friend thinks this is a trick question lol).
Answer:
To answer this question you have to think, "What am I really" to answer that you are your brain. When you say "am I thinking whenever I have a desire to" your brain is the "I." You think when your brain wants you to think. It rules everything that happens. It creates thoughts and commands all parts of the body.

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.

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.

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.

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.

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.

How do different types of forces affect objects?
ITS 58 POINTS!
Answer:
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. Remember that acceleration is a change in velocity.

How will you find the valency of chlorine, sulphur and magnesium
Answer:
Explanation:
ANSWER
If the number of electrons in the outermost shell of an atom of an element is less than or equal to 4, then the valency of an element is equal to the number of electrons in the outermost shell.
If it is greater than 4 then, the valance is determined by subtracting the outermost shell of electrons from 8.
The electrons in Cl, S, and Mg are 2,8,7 ; 2,8,6 ; 2,8,2
Hence the valency of Cl, S, and Mg are 1, 2, 2 respectively.
Answer:
Chlorine has 7 valence electrons
Magnesium has 2 valence electrons
Sulphur has 6 Valence electrons
Explanation:
We can find how many valence electrons by looking at the periodic table. For instance chlorine is a halogen and therefore has 7 valence electrons as it is in group 17. Magnesium is in group 2 so therefore has 2 valence electrons.
Sulphur is in group 16 and therefore has 6 valence electrons.
If the group has double digits I.e 16 like sulphur we only look at the second digit i.e. 6 as we can't have more than 8 valence electrons.
