Which is required for sexual reproduction? 1.mitosis 2.binary fission 3.diploid cell production 4.meiosis

Answers

Answer 1

Answer:

4. Meiosis

Explanation:

Mitosis creates cells for growth and repair, not for sexual reproduction. Binary fission is a form of asexual reproduction, not sexual reproduction. Diploid cell production is mitosis (mitosis creates diploid cells, or cells with a full set of chromosomes)

Meiosis is the correct answer. Meiosis creates gametes or sex cells that are necessary for sexual reproduction. Through this cell division process, 4 gametes are produced. The cells that are produces are haploid, which means they only have half of a full set of chromosomes. The cells are haploid because, during fertilization, a sperm (male sex cell) and egg (female sex cell) fuse. The result is a diploid zygote with half of the genetic information from the father and the other half from the mother.

The correct answer is 4. Meiosis.

Answer 2

Answer:

its D. Meiosis

A medical test indicates that a patient has a defective protein. This

condition is most likely due to a change in the directions coded in the:


number of phosphate molecules

sequence of subunits in DNA

number of nitrogen bases

sequence of sugar molecules

Answers

Answer:

number of nitrogen bases

Explanation:

The correct answer would be the number of nitrogen bases.

A defective protein is usually caused by mutation, which is defined a change in the DNA sequence of an organism.

Mutation can occur in a variety of ways including:

1. Deletion of nucleotide base sequence in the DNA

2. Addition (insertion) of nucleotide base sequence in the DNA

3. Duplication of nucleotide sequence in the DNA

A change in number of phosphate molecules, sequence of subunits DNA and sequence of sugar molecules if possible in nature, do not lead to mutation if the change does not affect the sequence of DNA.

Hence, the correct option is number of nitrogen bases.

1.33 dandelions per square meters

Explanation:

The correct answer would be 1.33 dandelions per square meter of land.

Size of quadrat = 1.5 square meters

Average number of dandelions per quadrat = 2

Total study area = 4500 square meter

Population density = number of organisms per unit area

There were 2 dandelions per 1.5 square meters

How many would be per square meter?

= 2 x 1/1.5 = 1.3333 dandelion per square meters

To 2 decimal places = 1.33 per square meters

Explain the unique bonding properties of carbon.

Answers

Atomic number of carbon = 6.Electronic configuration has 2 electrons in k shell and 4 electrons in L shell.In order to attain the noble gas configuration, carbon should either gain 4 electrons or lose 4 electrons or can share it's 4 electrons with some other element.Gain of 4 electrons to form octet , 8 electrons in C⁴‐ anion is difficult because then a nucleus with 6 protons will uave to hold extra four electrons. Loss of 4 electrons to attain duplet , 2 electrons like He atom in C⁴+ cation is difficult as it requires large amount of energy to remove four electrons. Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements. These electrons contributed by the atoms for mutual sharing in order to acquire the stable noble configuration is called covalency of that atom . Hence carbon shows tetracovalency.The simplest molecule formed by sharing electrons, cvalent bonds can represent by electron dot structure.

Carbon , hence overcomes this difficulty by sharing its four valance electrons with other atoms of carbon or with atoms of other elements.

What do you mean by valence electrons?

A valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed.

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.

For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table.

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “Green pods” appear?

1.A and D  2.B and E  3.A,C and D  4.A,B,C,D and E

Answer:

3.A,C and D

Explanation:

As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.

As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Which type: Land breeze or sea breeze would most likely form on a warm, cloudless, summer day? How do you know? Explain

THXSSS PLEASE HELP AND HURRY

Answers

Answer:

Explanation:

Sea breeze is a breeze that comes from the ocean to the land. The breeze is usually more when the temperature difference between land and ocean is high especially when it is summer and hot afternoon.

When the temperature is hot both land and water are been heat up, the land begin to release heat and warm air will rise over the land. Water do not get heat up easily hence the air is cooler leading to high pressure on the ocean air then blows from here to the land.

Answer:

Sea breeze.

This is because sea breeze occur on hot summer days which is due to unequal heating on the land surface and sea surface

Explanation:

Land and Sea breezes are as a result of different rate of heating on land or sea surfaces along coastal areas.

Sea breeze occur in a warm, cloudless summer days because of the unequal heating of the land and water surfaces.

During the day, the land surface heat more that the water surface. The air that is above the land become warm and it is warmer than that on the sea surface but the warm air is lighter than cool air. The warm air above the land surface rise, and the cool air on the sea surface rises and replaced the land warm air . This is sea breeze

Which statement is a counterclaim to the argument that schools should require students to participate in sports?The Pros and Cons of Sports Schools should make participation in sports compulsory for students. Sports help children to not only channel their abundant energy in the right way, but also to become physically healthy and strong. Nowadays, children experience a sedentary lifestyle as they mostly remain indoors with their laptops or mobile phones. Sports would be a means of recreation, and it provides students with an opportunity to interact with other children of their age. Sports also help children de-stress and develop traits such as perseverance, discipline, and team spirit. By playing sports, children realize that a game is not simply about losing or winning but also about their attitude toward the victory or the loss. The spirit of sportsmanship can help one build good relations with people and go a long way in life. Parents, however, often voice the concern that time spent on sports can adversely affect a child's academic performance. Most often, children devote a lot of time to games and sports. As a result of this, they have no time to work on assignments or attend remedial classes. Even if they do try to study, they would be too tired to pay attention or understand the content. Playing sports can cause physical injuries, which not only forces students to miss classes in school but can also lead to serious health issues. But current research studies have found that participating in sports increases students' overall academic performance. So, parents are obviously wrong and need to do more research. Therefore, it is very important that children learn to balance their studies and sports.A.)
