Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
Explanation:
Hope this helps.
Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.
What is meiosis?Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.
There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.

Which of the following does not describe a source of greenhouse gases?
Steam of fossil fuels
Burning of fossil fuels
Freezing of permafrost
Emissions from landfills
Answer:
i think its C) Freezing of perma frost
Explanation:
The option that does not describe a source of greenhouse gases is the freezing of glaciers. Thus, the correct option is C.
What are greenhouse gases?Greenhouse gases may be defined as those gases that are present in the earth's atmosphere and trap the heat and radiation from the sun and emitted toward the earth.
Such greenhouse gases are responsible for the greenhouse effect that ultimately leads to global warming.
Steaming and burning of fossil fuels and emissions from landfills extremely liberated the high amount of carbon dioxide in the atmosphere which is one of the most potent greenhouse gas.
Therefore, the option that does not describe a source of greenhouse gases is the freezing of glaciers (hailstone). Thus, the correct option is C.

If 2x 2 + 13x – 7 = 0, then x could equal to which of the following?
Answer:3/13
Explanation:
Answer:
x = 1/2 and x = -7
Explanation:
you need to factor
multiply 2 x -7 to get -14
then find factors of -14 that add to give you 13
14 and -1 work
now rewrite the original equation but replace 13x with 14x - 1x
so 2x^2 + 14x - 1x -7 = 0
now factor by grouping
(2x^2 + 14x) (-1x - 7) = 0
factor the greatest common factor out of each group
2x(x + 7) -1(x + 7) = 0
the factors are (2x - 1) (x + 7) = 0
set each factor equal to zero and solve both for x
2x - 1 = 0 x + 7 = 0
+1 +1 - 7 - 7
2x = 1 x = -7
÷2 ÷2
x = 1/2

When referring to cell division, oncogenes are most like ________ while tumor suppressor genes are most like ________. the brakes on a car; the gas pedal on a car the steering wheel on a car; the gas pedal on a car the gas pedal on a car; the brakes on a car the brakes on a car; the steering wheel on a car
Oncogenes are most like the gas pedal on a car, while tumor suppressor genes are most like the brakes on a car. Oncogenes and tumor suppressor genes are mutated in cancer cells.
Oncogenes are genes overexpressed in cells in which they should not be expressed, thereby leading to cancer.
Some examples of oncogenes are growth factors such as, for example, the Platelet-derived growth factor (PDGF) or Epidermal growth factor (EGF).
Conversely, tumor suppressor genes are genes that act to regulate cell division and replication, thereby their inactivation also leads to cancer.
A well-known example of a tumor suppressor gene is the p53 gene that acts to control cell division and apoptosis (programmed cell death).

How are the amounts of carbon dioxide and oxygen inhaled by lungs different from the amounts exhaled? How do cellular respiration and the law of conservation of mass relate to this?
I NEED HELP!!
Answer:
1. Gas exchange takes place by diffusion in the alveoli within the lungs. As a result the composition of inhaled and exhaled air is different.
...
Inhaled and exhaled air.
Gas % in inhaled air % in exhaled air
Oxygen 21 16
Carbon dioxide 0.04 4
Nitrogen 79 79
NB These figures are approximate.
2. The amount of carbon-dioxide atoms released by respiration are exactly equal to the atoms of these materials contained in the oxygen and carbon converted. In this way respiration has conserved the mass or material and in this way followed the law of conservation of mass.
Explanation:
What is Cellular Respiration?
Cellular Respiration is the process in which the cells of living things break down the organic compound glucose with oxygen to produce carbon dioxide and water. The overall chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (stored in ATP)
Cellular respiration takes place in the cells of all organisms. It occurs in autotrophs such as plants as well as heterotrophs such as animals.
Q: How is cellular respiration related to breathing?
A: Breathing consists of inhaling and exhaling, and its purpose is to move gases into and out of the body. Oxygen needed for cellular respiration is brought into the body with each inhalation. Carbon dioxide and water vapor produced by cellular respiration are released from the body with each exhalation.
Energy Changes in Cellular Respiration
The reactions of cellular respiration are catabolic reactions. In catabolic reactions, bonds are broken in larger molecules and energy is released. In cellular respiration, bonds are broken in glucose, and this releases the chemical energy that was stored in the glucose bonds. Some of this energy is converted to heat. The rest of the energy is used to form many small molecules of a compound called adenosine triphosphate, or ATP. ATP molecules contain just the right amount of stored chemical energy to power biochemical reactions inside cells.

Fungi, Monera, and Protista are the three kingdoms he neglected to mention.
What Linnaeus classification?The Linnaean system is based on similarities in apparent physical qualities. This system is a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The domain, which was just added and is a larger taxon, is smaller than the kingdom. Seven levels make up Linnaeus' hierarchical classification scheme. They are kingdom, phylum, class, order, family, genus, and species, in order of largest to smallest. Linnaeus created a hierarchy for nature in Systema Naturae. He suggested that the entirety of nature may be divided into three big categories known as kingdoms. Animals, plants, and minerals made up these three kingdoms. He categorizes each of these kingdoms.To learn more about Linnaeus classification refer to:

Which of the following is a disadvantage of genetic engineering?
May cause negative side effects
Cannot create new organisms
Reduces the nutrition value of food
Increases the scarcity of food in the world
Answer:
may cause negative side effects
Explanation:
Answer:
May cause negative side effects.
Explanation:
I took the test
Genetic Engineering is used to put genes from one organisms into another. The new organism can reproduce. And while it may seem like it's the answer the nutrition value and scarcity of food is in no way impacted. It's not like cloning. Where more are being created in large amounts with similar diets. They can be cross-pollinated with organisms with different diets. So the only obvious answer would be the negative side effects.

Joe, age 14, recently fractured his forearm midway between his wrist & elbow. Should his physician be concerned about his epiphyseal plate being affected and causing bone growth to stop?
Joe's doctor must be concerned that his bone growth will be hampered by damage to the epiphyseal plate.
We can arrive at this answer because:
The epiphyseal plate is a set of cartilage present at the end of long bones, such as the bones present in the forearm.The epiphyseal plate is responsible for the longitudinal and lateral growth of the bone.This growth occurs during childhood and adolescence, for this reason, it is essential to maintain the good integrity of this plaque during this time of life.In the case of Joa, who is still a teenager, a fractured forearm can damage his epiphyseal plate and affect his body's bone growth, so his doctor should be concerned about this.
It is important to note that during adult life, the epiphyseal plate is replaced by an epiphyseal line.
