How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.

How do metamorphic rocks work?
Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

These limbs provide evidence of common ancestry because they -
Answer
A have the same basic structure
B pedom the same function
С
are the same size
Dare parts of mammals
Answer:
The answer is A
Explanation:
All the the different limbs all have an upper arm bone which is the humerus and two forearm bones which are the ulna and the radius.
The limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.
What is a common ancestor?A common ancestor may be defined as an ancestral organism that is significantly shared by two or more descendent lineages. In a more simple term, an ancestor that they have in common. These ancestors follow each taxon's lineage back in time until all the lineages meet up.
A Common Ancestor is a lineage that undergoes cladogenesis, that is, branching evolution, such that more than one species can trace its ancestry back to the common ancestor or, more accurately, to multiple common ancestors.
Therefore, the limbs of Whales, horses, birds, cats, and humans provide evidence of common ancestry because they have the same basic structure. Thus, the correct option for this question is A.

Your skin cells have 46 chromosomes. After they complete the cell cycle, how many chromosomes will be in the daughter cells? Explain.
Answer:
46
Explanation:
The skin cells with 46 chromosomes will each produce daughter cells with 46 chromosomes after they complete the cell cycle.
The skin cell is a vegetative cell that can only divide through mitosis. Mitosis is also referred to as equational division during which a cell produces two daughter cells that are both genetically and phenotypically similar to the parent cell.
During the cell division, at the anaphase stage to be precise, the chromosomes are separated into sister chromatids and sister chromatids of the same chromosomes move in the opposite direction to the poles of the cell before the cytoplasm of the mother cell divides to produce two independent daughter cells. Each chromatid in the new daughter cells then goes ahead to become a complete chromosome with two sister chromatids.
Hence, at the end of the cycle, each daughter cell ends up having the same 46 chromosomes as the parent cells.
What is the relationship between changing co2 concentration and temperature?

Explanation:
The table below shows the percentages of bases in a DNA sample. How much Guanine (G) should you expect to find in the sample?
Answer:
17%
Explanation:
guanine is cooped
with cytosine
Using Chargaff's rule, the percentage of Guanine(G) in the sample is always equal to the percentage of Cytosine. Hence, the percentage of Guanine which is expected to be found in the sample ls 17%.
From the table attached :
Thymine = 33%Cytosine = 17%According to Chargaff ; the percentage of Cytosine equals the percentage of Guanine :
Guanine = Cytosine = 17%.
Percentage of Thymine equals the percentage of Adenine :
Adenine = Thymine = 33%Therefore, the amount of Guanine which is expected to be found in the sample is 17%

Answer: i think it is domains kingdoms
Explanation: based on their cell types
What are some ways that living things can be classified? What characteristics should we look at when putting living things into groups?
The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things.
