Can you please help me with this?
Answer:
The population of peppered moths thrived, because they camouflaged with the bark of the trees, thereby they were not easily seen by predators. Black moths were easily seen by predators and they were eaten as a result. Because the black moths did not survive, they were unable to reproduce offspring with those traits. However, peppered moths were able to reproduce offspring that were also peppered. During the industrial revolution, the colour of the bark darkened. This meant the peppered moths were easily seen by predators, so they were eaten. Black moths camouflaged with the bark, so now they weren't easily seen by predators. Now that the black moths survived, they could reproduce more black moths. But peppered moths weren't able to reproduce more peppered moths because most didn't survive. This is an example of how an abiotic factor, such as bark can affect a population of a species. Because the bark influenced the survival of the moths, some moths with the desirable traits survived, and others with the undesirable traits died.

Oxygen gas production will happen within me
Answer:
Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar molecules fructose and glucose. Green plants use energy from sunlight to build sugar molecules from carbon dioxide and water.
Plant cells contain organelles called chloroplasts that are essential for photosynthesis. Within chloroplasts, oxygen gas production will take place. So, the answer is chloroplast.
Plants use sunlight, water, and carbon dioxide to produce oxygen and sugar-based energy through a process known as photosynthesis. The process of photosynthesis results in the emission of oxygen gas.
Photosynthesis and release of oxygen processes occur within chloroplasts that generate energy that support plant growth and crop yield.
Although mitochondria are organelles that can be found in plant cells, they do not produce oxygen. Cellular respiration is carried out by mitochondria. Although cellular respiration consumes oxygen gas, it does not create oxygen gas.
Therefore, chloroplasts is the answer to the question "Oxygen gas production will happen within."

A student keeps an onion bulb in a jar filled with water and observes that the roots continue to grow in length. The student cuts a root tip and observes it under a microscope. The image shows the observations. Which option supports the reason for an increase in the root’s length?The root cells undergo meiosis to expand and increase in length.
The root cells undergo mitosis to combine together to make the root grow.
The root cells undergo mitosis to form new identical cells.
The root cells undergo meiosis to form different types of cells.
Answer:
The root cells undergo mitosis to form new identical cells.
Explanation:
Mitosis is the process of cell division, where a cell divides into two equal cells with the same number of chromosomes. These new cells are used to promote the growth of a biological structure, promoting an elongation, a replacement, a concert, or an increase in volume. This can be seen in the case of the growth of the tip of the onion root, where the cells underwent mitosis, forming equal cells, to promote the growth of a new tip.
Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swaps genetic information with a different chromosome (this is NOT Crossing Over). O Inversion O Duplication O Deletion O Translocation
Answer:
The correct answer is ''Translocation.''
Explanation:
Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.
how do flowering plants reproduce asexually and sexually?
Answer:
Plants reproduce sexually by dropping pollen into another flower. This pollen can go into a flower or, it can drop to the grass. That's when asexual reproduction comes in. The ground absorbs the pollen and the pollen acts like a seed, making a new plant.
See the attached picture if you wanna know what pollen looks like.

Think about the meaning of these words fruit seed germinate cotyledons, embryo ,plumule ,dormancy,root hairs. Write a sentence containing each of these words
Answer:
When a seed, taken from a fruit, is planted and watered under the correct temperature, it breaks dormancy, and the embryo germinates; first, the root grows covered by root hairs, then the cotyledons appear, and finally, the plumule elongates to reach the light.
Explanation:
Fruit: It forms by the mature ovary of the flowers. This structure contains and protects the seeds in its interior. Its principal function is to transport seeds to a distant area away from the parental plant and let the new plant emerge under the correct environmental conditions. The fruit develops different strategies to accomplish its function. Seed: Refers to the fecundated and mature ovule. This structure is the typical dissemination and dispersion unit of spermatophyte plants. Seeds are formed of three tissues. An embryo. A seminal tegument that covers and encloses the latent embryo. And the endosperm -a nutritious tissue-. Seeds develop and grow under the protection of the fruit body. Embryo: It is formed after fecundation. It composes of growing cotyledons, an epicotyl, and a hypocotyl. The tegument and endosperm of the seed protect the embryo from dehydration and denutrition. Once the seed is in the correct place, the embryo grows and emerges. Cotyledon: The two first leaves of the embryo. They have reserve nutritive tissues to help the embryo grow. It also performs photosynthesis. The embryo usually develops one or two cotyledons and one radicule or root hair. Plumule: First shoot of the young emerging plant. When the embryo is growing, it elongates to reach more sunlight. Root hairs: Extention of the roots´ cells that look like hairs and whose principal function is to absorb nutrients and water from the ground. They can be found in the maturation area of the root. Germination: Process of development and the emergence of the embryo. These are a series of steps that must occur in the seed from the moment the embryo begins to develop until a newly emerged plantule is formed. For germination to occur, there must be the appropriate environmental conditions. Dormancy: Period in which an alive seed can not germinate because there is a condition inside the seed that does not allow germination to occur yet. The seed is in dormancy, but it keeps viability.Most biology textbooks prior to 1990 listed the major function of ribonucleic acid (RNA) as transferring information from DNA to make proteins. In late 1989, Thomas Cech proposed that RNA had a second major function: as a catalyst for chemical reactions that occur inside the cell. His discovery surprised most scientists and caused the rewriting of many chapters in biology textbooks. What aspect of the scientific process does this best illustrate?
Answer:
The correct answer would be - overgeneralization of a hypothesis.
Explanation:
In this case, the scientist uses to think and listed the transferring information from DNA to make proteins as the main and major function of the RNA until Thomas Cech proposed that it is the second most important catalyst that takes place in the cell and catalyzes cell's chemical reactions.
This illustrates major aspects of the scientific process: overgeneralization of a hypothesis as RNA is not just a molecule that assists and transfers the information but new evidence found it has catalytic activity also.

Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is CC were to have children with a person who is cc, could it be possible for them to have a child with straight hair?
a
yes
b
no
Answer:
No, it would not be possible to have a child with straight hair.
Explanation:
The Punnett cross would be CC x cc, so all the offspring would be Cc. Since straight hair is only cc, the kids would not have straight hair.
Awnser:
yes, it is possible :)
Explanation:
Their children would would have the dominant trait, curly hair, and the recessive straight hair gene hidden in their dna. If there was a chance that one of their curly haired children met with a cc-partner with straight hair, then they would have a 1 in 2 chance. Even with a Cc-partner, there would be a 1 in 4 chance of the straight hair trait "skipping a generation".
