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."

history of fossil fuels & how fossil fuels are formed
Answer:
Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure
Why are the oceans movements along the shore called waves? What do ocean waves have in common with sound and light
Answer:
It has crust and trough.
Explanation:
The oceans movements along the shore called waves because it has crust and trough just like waves and vibrates about its mean position. A crest is a higher point of wave whereas trough is the opposite of a crest and lowest point of a wave. Ocean waves is similar to sound and light waves because both waves travel as up and down vibrations and the energy present in these wave travels in forward direction.

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.What body shape do typical jellyfish have?

As a part of the life cycle of plants, the plant must begin with an embryo. What statement best describes where the embryo can be found in flowering and non-flowering plants?
The missing statements are given as follows:
a. In a flowering plant, the embryo is in seeds found in the flower, and in non-flowering plants, the embryo is in seeds found in the cone.
b. In a non-flowering plant, the embryo is in spores found in the stem, and in a flowering plant, the embryo is in seeds found in the flower.
c. In a non-flowering plant, the embryo is in seeds in the leaves, and in a flowering plant, the embryo is in seeds found in the spores.
d. In a flowering plant, the embryo is in spores found in the flower, and in a non-flowering plant, the embryo is in seeds found in the spores.
Answer:
The correct answer is - option a. In a flowering plant, the embryo is in seeds found in the flower, and in non-flowering plants, the embryo is in seeds found in the cone.
Explanation:
Non-flowering plants especially gymnosperms begin their life cycles from the embryo found inside the seeds like the flowering plants however, in gymnosperms these are found in the cone.
In the flowering plants, the embryo is present in the seeds present in the flower that develop into fruits too. Angiosperms are the flowering plants that produce seeds.
Thus, the statement best describes where the embryo can be found in flowering and non-flowering plants.
Answer:
In a flowering plant, the embryo is in seeds found in the flower, and in non-flowering plants, the embryo is in seeds found in the cone.

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.

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.
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".
