The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration
Answer:
They work together to regulate water loss and gas exchange.
They work together to regulate the loss of water and exchange of gases.
Stomata and guard cellsThe tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.
The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.
Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.
Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

differentiation of tissues
Answer:
1. Mitotic cell division
Explanation:
Embryonic development is the formation of organisms that starts from the process of fertilization. The stages of development represent mitosis.
What is mitosis?Mitosis is a part of the cell cycle, that produces two identical nuclei and daughter cells from the division of the cell and replication of the parent cell.
From the diploid parent cell, two diploid daughter cells are produced in mitosis. This process is the first and the initial stage of embryonic development that initiates the growth and development of the embryo from the parent cell.
Therefore, option 1. mitosis is the process of embryonic development.

what is the possible liminations of using hair as evidence in crime investgation s\
Answer:
A limitation of using hair as evidence from a crime scene is that hair can not be directly linked to a suspect. It is impossible to say that a hair sample came from only one specific person.
Answer:
How it got there. Anyone's hair can be carried and blown from anywhere, if so you'd have to go through every persons dna that had contact with a victim and contact with the contactie and so on and so on.
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".

How does gene expression differ between human fibroblasts and induced pluripotent stem cells (iPS)?
Answer:
Both have different gene expression due to produce from different sources.
Explanation:
Gene expression is different between human fibroblasts and induced pluripotent stem cells because both cells are formed from different sources. Human fibroblasts is produced from ''mesenchyme'' a type of connective tissue whereas induced pluripotent are the stem cells which can be produced from adult cells so we can say that both have different gene expression.
Both have different gene expression due to produce from different sources.
The following information should be considered:

dose DNA have cells
i need to know for a assingment
Answer and Explanation:
Cells are made of DNA (Deoxyribonucleic Acid).
They provide the genetic instructions for making and forming a cell.
The DNA is found inside the nucleus of the cell.
Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. This packaged form of the DNA is called a chromosome
DNA do NOT have cells, but cells DO have DNA.

- True or False. The arrow labeled A represents a transfer of solar energy to chemical energy. Explain why this is true or false.
- Which arrow or arrows represent a release of carbon dioxide? What process is occurring at the arrow(s) you selected?
- Which arrow or arrows indicate a process that cycles carbon from living or nonliving organisms? Describe the process or processes you selected.
- Which arrow or arrows represent reactions that demonstrate a conservation of mass and energy? Explain your answer.
Answer:
FALSE. The factory uses mechanical energy and when carbon is released into the atmosphere it is the process of chemical energy. ... Arrows C + F represent a release of carbon dioxide. Arrow C shows carbon being released into the air from the factory.Its true because the arrow letter A uses the of solar power from the sun then makes a chemical reaction to make food for the plant so basically photosynthesis. 8.arrow E represents cycling of carbon from living organisms to non-living organisms. this is because it is showing conversion of a carbon from the dead tree to fossil fuel.All the arrows in a combined form are used to show the biogeochemical cycle or the carbon cycle. In this cycle, carbon is cycled between the biotic and abiotic component of the biome. In any biogeochemical cycle, mas and energy are always conserved.A bee gets nectar from a flower and the flower gets help with pollination.

Compare the composition of Nucleic acids to lipids
The smooth endoplasmic reticulum also processes these lipids, which store energy.
Nucleic Acids: Carry genetic information or form structures within cells. Carbohydrates: storage and transport of energy and structural components.
Proteins: Many proteins are enzymes that catalyze biochemical reactions, and are vital to metabolism.
In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would MOST affect the action of the enzyme?
Answer: The environmental factor that would most affect the action of enzymes in the conversion of carbon dioxide into glucose (photosynthesis ) is the light.
PHOTOSYNTHESIS - Photosynthesis is a process by which plants and other organisms convert light energy into chemical energy, which is then released to fuel the organism's metabolic activities through cellular respiration. Carbohydrate molecules, such as sugars, store this chemical energy, which is created from carbon dioxide and water.
The first photosynthetic species most likely arose early in the evolution of life and used reducing agents such as hydrogen or hydrogen sulfide as electron sources rather than water. In the process of carbon fixation, carbon dioxide is transformed into sugars; photosynthesis uses energy from the sun to turn carbon dioxide into carbohydrate. Carbon fixation is a redox reaction that is endothermic. Photosynthesis is the oxidation of carbohydrate or other nutrients to carbon dioxide, while cellular respiration is the reduction of carbon dioxide to carbohydrate. Carbohydrates, amino acids, and fatty acids are nutrients involved in cellular respiration.
Do mutations in body cells contribute to genetic variation?(1 point)
A) No, the causes of body cell mutations are outside the body and cannot alter DNA.
B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.
C) Yes, these body cell mutations lead to mutations in the gametes.
D) No, the mutations cannot be passed to offspring and only affect the individual.
A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.
The correct answer is:
Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.
Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.
The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.
The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.
Therefore Option B is correct.
