D. phloem

Answers

Answer:

xylem & phloem are present in both woody and herbaceous stems

Explanation:

Vascular system is present in both, woody and herbaceous stems. Thus, option A, and D are correct.

What are vascular tissues?

In vascular plants, A tissue which is complex in nature, formed by more than one type of cells are called as vascular tissues. Two main types of vascular tissues are:

XylemPhloem

The transportation of water from roots to stem and leaves of the plant is carried out by xylem. Xylem consist of tracheids and vessel elements, which have different characteristics,  but both play significant role in transportation of water and nutrients.  

The soluble organic compounds synthesized during photosynthesis in the plants are transported by another vascular tissue called as phloem, in process called translocation. It consists of sieve elements, parenchymal cells, fibers, and sclereids.

Therefore xylem and phloem are present in both, woody and herbaceous stems.

Michael discovers that a fish breathes less often in cool water. He correctly hypothesizes that A. the fish slows down in cool water, and does not need as much oxygen. B. the fish is eating, and does not have time to breathe as much. C. the fish is sleeping, and does not need as much oxygen. D. there is less oxygen in cool water, so the fish breathes slowly.

Answers

Answer: then it’s d there is less oxygen in cool water

Explanation:

There are many explanations for Michael's observation that fish breathe less frequently in cold water. However, his hypothesis that the fish returns to the cold water and requires less oxygen seems possible.

What type of animals fish are?

Fish are cold-blooded animals, which means their environment controls their body temperature. Their metabolic rate, activity level, and oxygen requirements decrease as water temperatures drop.

As a result, fish can slow down in cold water, reducing their oxygen demand and reducing their breathing rate.  Oxygen solubility may also play a role in whether fish breathe less in cold water. As the water temperature decreases, the ability of oxygen to dissolve in the water also decreases. Because of this, cold water can have less oxygen available, which can cause fish to breathe more slowly to compensate for the lack of oxygen.

Because fish need oxygen to digest food, they are likely to eat and breathe less. It's basically a joke that the fish are resting because fish don't have an obvious resting cycle and will move and swim when they are resting.

Finally, Michael's hypothesis that fish breathe less in cold water is plausible as it suggests that fish slow down and don't need as much oxygen.

Infinity of biology ​

Answers

Answer:

Origin: L. Infinitas; pref. In- not – finis boundary, limit, end: cf. F. Infinite. See Finite.

1. Unlimited extent of time, space, or quantity; eternity; boundlessness; immensity. There can not be more infinities than one; for one of them would limit the other. (Sir W. Raleigh)

2. Unlimited capacity, energy, excellence, or knowledge; as, the infinity of god and his perfections.

3. Endless or indefinite number; great multitude; as an infinity of beauties.

4. (Science: mathematics) a quantity greater than any assignable quantity of the same kind.

Mathematically considered, infinity is always a limit of a variable quantity, resulting from a particular supposition made upon the varying element which enters it.

5. (Science: geometry) That part of a line, or of a plane, or of space, which is infinitely distant. In modern geometry, parallel lines or planes are sometimes treated as lines or planes meeting at infinity. Circle at infinity, an imaginary circle at infinity, through which, in geometry of three dimensions, every sphere is imagined to pass. Circular points at infinity. See Circular.

A red animal (AA dominant) mates with a yellow animal (aa recessive). What would be the genotype and phenotype of a heterozygous offspring? (Assuming
complete dominance)
a.phenotype (yellow): genotype Aa
b.phenotype (red); genotype AA
c.phenotype (yellow); genotype aa
d.phenotype (red): genotype Aa

Answers

Answer:

d.phenotype red: genotype Aa

Explanation:

a red animal that is a Donna Mae a would still have dominance over the yellow animal it recessive so if you put it in the chart form AA would be on top and the lowercase a a would be on the left side so it would be phenotype red genotype capital a lowercase a .

In codominance, the genotype of the cross will be Aa and the phenotype will be yellow. Therefore, option "A" is correct.

What is codominance?

Codominance is a genetics-related term. The term means a type of inheritance, where two versions (alleles) of the same gene are expressed separately. This lead to the yield of different traits in the offspring. Examples are when in animals such as speckled chickens, having alleles for both types of feathers, black and white.

Roan cattle is also an example of co-dominance, which expresses alleles for both red hair and white hair. Codominance is also present in plants. Examples are rhododendrons which have a simultaneous expression of red and white genes for flower color display flowers with both red and white petals.

DNA or deoxyribonucleic acid is a structure which is common in every living organism. The two strands of the DNA are held together by base complementarity between the nitrogenous bases these bases are held by hydrogen bonding. Adenine always pairs with thymine by a triple hydrogen bonding and cytosine is always forms a pair with that of guanine by a double hydrogen bonding. So, in this given situation cytosine or C will show complementarity with that of guanine or G in a DNA structure helping in linking the two strands of DNA to form a single integrated double helical structure.

one wave per second. Suppose a person
counted 10 waves passing by over a time
period of 1 second. What is the wave
frequency?

Answers

Answer:

it will be 10Hz ,because number of waves per second is 10 so we divide with 1second

The wave frequency of a wave which is passing by 10 waves over a time period of 1 second will be 10 Hertz (Hz).

What is Wave frequency?

Wave frequency can be defined as the number of waves which are passing through a fixed point in a given amount of time period. The SI unit for the wave frequency is the hertz (Hz), where 1 hertz is equal to 1 wave which is passing through a fixed point in the time period of 1 second. A higher-frequency wave has generally more energy than a lower-frequency wave with the same magnitude of amplitude.

Which of the following is the reason in how the anterior pituitary differs from the
posterior pituitary?
O A) the hypothalamus controls the release of posterior pituitary hormones but not the anterior
pituitary
B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic
hormones
C) the posterior pituitary works independently of the hypothalamus
D) the anterior stores hormones produced by the posterior pituitary

Answers

Answer:

B) the anterior pituitary makes its own hormones; the posterior pituitary releases hypothalamic hormones

Explanation:

The pituitary gland is referred to as "master gland" because it coordinates the activities of other endocrine glands. The pituitary gland is composed of two lobes namely: anterior pituitary and posterior pituitary. These two lobes are individually controlled to release several hormones by the HYPOTHALAMUS.

However, one major difference between the anterior and posterior pituitary lobe is that; the posterior pituitary DOES NOT MAKE ITS OWN hormone, hence, releases the hormones (oxytocin and ADH) it stores but produced by the HYPOTHALAMUS. On the other hand, the anterior pituitary PRODUCES ITS OWN hormones but waits for hypothalamic signal to release them.

A random mutation occurs and the GGA codon is changed to CGA, what effect does the substation have on amino acid

Answers

Answer:

The replacement of a base at a codon, as occurs when the GGA codon is changed to CGA, causes a change in the amino acid glycine to arginine.

Explanation:

Nitrogen base changes in a codon usually result from base changes in the DNA before transcription into mRNA,called point gene mutations.

In the case presented, the substitution of the guanine base by cytosine in the GGA codon--resulting in a CGA codon--generates a change in the coding amino acid resulting in arginine instead of glycine.

The change of an amino acid in a peptide or protein can mean an alteration in the structure or function of these molecules.

Because an amino acid can be encoded by several codons, changes of a nitrogen base at a codon sometimes do not involve changes in the amino acid sequence of a protein.
