Which of these are present in both woody and herbaceous stems? (Select all that apply.)
A. xylem
B. rings
C. seedlings
D. phloem
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:
XylemPhloemThe 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.

Modern research has indicated that the appendix has at least one important function _____.
Modern research has indicated that the appendix has at least one important function _____.
a storehouse for good bacteria
fights intestinal infection
aids in digestion
secretes hormones
produces insulin
Answer:
The correct answer is - a storehouse for good bacteria.
Explanation:
The appendix is a finger-like small narrow-sized pouch that founds out from the colon. Initially, it was thought to a vestigial organ that has very little or no function in the human body.
In modern and more recent research suggests that the appendix has a very important role as it works as a reservoir or storehouse for beneficial gut bacteria.

Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH is his real belts appear in the table below
Answer:
B. Enzymes have particular pH's at which they function best
Explanation:
The table in this question describes the reaction rate of two enzymes (enzyme 1 and 2) measured in mmol/min. According to the question, Greg performed an experiment in which he measured the reaction rate of two different enzymes at varying pH.
At pH 7-9, the reaction rate of enzyme 1 was more than that of enzyme 2 while from pH 9.5-11, the reverse was the case. This portrays that the reactivity of an enzyme is in response to the pH they are placed in. In other words, different enzymes have particular pH's at which they function best.
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
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.

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.
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.

What has changed in the world that has resulted in the drastic increase of carbon dioxide levels in the atmosphere?
Answer: On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

which of the following is an example of a complementary base pair in DNA?
a. A-G
b. T-C
c. A-U
d. C-G
Answer: d. C-G
Explanation:
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.

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

Infinity of biology
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.
