Answers

Answer:

Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant's root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.

Match each of the following terms with its description. 1. Arteries a) Tiny, thin-walled blood vessels that connect the smaller arteries to venules 3. Veins 4. Venules 5. Arterioles 2. Capillaries b) Thin-walled blood vessels that are less elastic than arteries c) Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles d) Small arteries that deliver blood to capillaries e) Small vessels that connect the capillaries to the veins

Answers

Answer:

Arterioles - D

Arteries - C

Veins - B

Capillaries - A

Venules - E

Explanation:

This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:

- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.

- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.

- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.

- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.

- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.

Why do you think leaves have stomata on their underside only? Explain.

Answers

The stomata must be open during the daylight hours to let oxygen and carbon dioxide pass through. While they are open, water vapor escapes into the atmosphere (transpiration). ... Transpiration is the loss of water through stomata, so, more stomata are found on the lower surface to prevent excessive loss of water.

In a lotus plant, stomata is found on the upper epidermis of the leaf.

Stomata are responsible for the exchange of gas with the surrounding atmosphere of the leaf. Their guard cells stay taut during the day to keep the stoma open.

Guard cells can only stay open if they are saturated with a certain quantity of water.

From this information we can infer that stomata are typically found on the lower epidermis to prevent water damage when it rains.

The rain would not only cover the openings, it would also ruin the osmotic balance of the guard cells causing inefficiency and damage to the cycle of gaseous exchange.

Natural selection probably selected against such plants giving rise to those with stomata on the underside.

"Draw a pedigree for hitchhiker’s thumb. Your pedigree should cover at least two generations and include both dominant and recessive forms of the trait. Label the pedigree with genotypes, using the letter H to represent the dominant allele for the trait and the letter h to represent the recessive allele."


I'm confused on the part about having two generations. How do I set up the pedigree?

Answers

Answer and Explanation:

First, you need to know how to interpret a pedigree representation.

Family members

→ Individuals are represented with geometrical figures.

→ Males are squares

→ Females are circles

Trait/Phenotype

→ Healthy/normal/not affected  individuals are represented with empty figures

→ Affected/mutated individuals are represented with solid black figures

Generations

→ Each file is represented with a roman number, indicating the Generation.

 

Now, what we need to do is to draw a pedigree for a hitchhiker’s thumb. We know that this is an autosomal dominant trait, which we will represent with an H. No hitchhiker's thumb is the recessive trait, and it will be represented with an h.

Our pedigree should cover at least two generations and include both dominant and recessive forms of the trait.    

We can cross two heterozygous individuals, Hh, who are the first generation in our pedigree. This cross will result in a woman and a man with No hitchhiker's thumb, another man with a hitchhiker's thumb, HH, and another woman with a hitchhiker's thumb, Hh. These individuals will represent the second generation in the pedigree. Finally, we can cross the man with No hitchhiker's thumb, hh, with a woman who does not have a hitchhiker's thumb either, hh. And the woman with a hitchhiker's thumb, Hh, with a man with a hitchhiker's thumb, HH. The result of these crosses will be the third generation.

The representation would be like following,

I → First-generation: First cross

Man Hh (1)  Woman Hh (2)

II → Second-Generation: F1 and second crosses

Man hh (3)  x    Woman hh (4)Woman hh (5)Man HH (6)Woman Hh  (7) x   Man HH (8)

III → Third-Generation:

A boy (9) and a girl (10) hhA girl (11) HH

You will find this pedigree in the attached files. In this example, we included three generations. The first one belongs to the grandparents, the second one to parents, aunts/uncles, and the third one to grandchildren.  

If you draw another pedigree, remember to include

the figures representing males and females, color and H/h representing the phenotype, Roman numbers representing the generations, and optional, numbers naming each member.

A __________ is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off. a protein b glyceride c nucleic acid d steroid e carbohydrate

Answers

Answer:

D. steroid

Explanation:

Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.

However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.
