When referring to mitosis where do the Chromosomes from during metaphase
Answer:
During metaphase, the cell's chromosomes align themselves in the middle of the cell through a type of cellular "tug of war." The chromosomes, which have been replicated and remain joined at a central point called the centromere, are called sister chromatids.
A diagram of a wave is pictured below. What does the length from A to B represent?
Answer:
wavelength
Explanation:
the distance between two successive crests or troughs of a wave is called wavelength
The diagram shows the distance between two successive crests or troughs of a wave, and it is called wavelength.
What is wavelength?Typically, wavelength is measured from crest to crest or from trough to trough in transverse waves with points vibrating at right angles to the direction of their advance.
It is measured from compression in longitudinal waves with points vibrating in the same direction as their advance.
It is a property of both traveling waves and standing waves, as well as other spatial wave patterns.
Therefore, It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.

Choose all the answers that apply. The atmosphere: is mostly made of nitrogen is weightless protects earth from harmful radiation contains water vapor is affected by events in the hydrosphere
Answer:
The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.
Explanation:
The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.
The Earth´s atmosphere is composed of water vapor, N₂ (78.08%), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. Water vapor might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. They protect the Earth from harmful radiation.
The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.

After TELOPHASE II of meiosis, what is the chromosomal makeup of each daughter cell?
Diploid, and the chromosomes are each composed of two daughter cells
Diploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of a single daughter chromosome
Haploid, and the chromosomes are each composed of two daughter chromosomes
plz remember its telophase 2 not 1
Answer:
Haploid, and the chromosomes are each composed of a single daughter chromosome
Explanation:
Meiosis is a type of cell division that reduces the chromosomal number of the daughter cells by half. Meiosis produces four daughter cells, which have half of the chromosomes of the parent cell. Meiotic process occurs in two division steps i.e. meiosis I and meiosis II, which each involves four stages namely: prophase, metaphase, anaphase and telophase.
- During meiosis I, homologous chromosomes (similar but non-identical chromosomes from parent), are separated into opposite poles while
- During meiosis II, sister chromatids (replicated chromosomes) separate into opposite poles.
Based on the above explanation, after TELOPHASE II of meiosis II, each daughter cell will be HAPLOID (n), and the chromosomes are each composed of a single daughter chromosome.

In human beings, the statistical probability of getting either a male or female child is 50:50. Give a suitable explanation.
Answer:
There is 50 chance because there are two chromosomes that are same and two which are difeerent . XX MEANs girl XY means boys .
➜ The sex of an infant is determined by the type of sex chromosome contributed by the male gamete. Since the ratio of male gametes containing X chromosome and those containing Y chromosome is 50:50, the statistical probability of male or a female infant is also 50:50.
2. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Which cellular organelle was most likely on the filter paper, and what process was it performing?
Answer:
Mitochondria; cellular respiration.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
The initial step in the formation of an aminoacyl-tRNA is Group of answer choices esterification of the tRNA activation of the tRNA by reaction with ATP activation of the amino acid by reaction with ATP interaction of the mRNA with the tRNA
Answer:
The initial step in the formation of an aminoacyl-tRNA is activation of the amino acid by reaction with ATP
Explanation:
In protein synthesis, the first step involves the formation of an aminoacyl-tRNA. This reaction is catalyzed by the the Mg²⁺-dependent enzymes known as aminoacyl t-RNA synthetases and occurs in two steps.
The first step of the reaction of the formation of an aminoacyl-tRNA is the activation of the amino acid by the attachment of an AMP molecule formed from the hydrolysis of ATP to AMP and pyrophosphate. The aminoacyl adenylate intermediate is bound to the enzyme in this initial step. Subsequently, in the second step of the activation of the amino acid, the aminoacyl adenylate intermediate is then transferred to its specific tRNA. The pyrophosphate formed in the first step is hydrolyzed to 2 phosphate molecules by a pyrophosphatase.
The overall reaction step is illustrated below:
Amino acid + tRNA + ATP -----> aminoacyl-tRNA +AMP + 2Pi

Friction is a force exerted in the direction opposite to an object's motion, which means friction will cause an object's
velocity to decrease.
-true or false?
Answer:
true
Explanation:
think of a box, if you push it on a smooth floor without friction it would glide pretty easy
but put it on say carpet, the friction from the carpet would not allow the box to move very far

Which two structures are part of the cortisol pathway?
Each gland consists of two parts: an inner medulla, which produces epinephrine and norepinephrine (adrenaline and noradrenaline), and an outer cortex, which produces steroid hormones.
The structures that are part of the cortisol pathway are the hypothalamus and liver.
Cortisol is a glucocorticoid in the brain with the function of operation of Gluconeogenesis and stress. The pathway of cortisol in the body is termed as cortisol pathway.
What structures are in the Cortisol pathway?The cortisol pathway is started with the release from the brain, targeting the hypothalamus. The release of epinephrine and nor-epinephrine is controlled with the cortisol release.
The release of the hormones targets the pituitary and adrenal gland and controls the release of stress hormones.
The gluconeogenesis process is controlled by the cortisol hormone. The process takes place in the liver.
Thus, the structures that are part of the cortisol pathway are the hypothalamus and liver.
