Answer:
C-Effects of poverty
Explanation:
The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
why do the other planets take longer to orbit the Sun than the inner planets do
Answer:
Outer planets take longer to orbit than inner planets because of the greater distance they need to cover. They also are further from the sun weakening the power of the suns gravitational pull which causes then to orbit slower.

A.
The 24 original chromosomes replicate, resulting in 48 chromosomes in the fertilized egg.
B.
The 24 original chromosomes split at the centromere, resulting in 48 chromosomes in the fertilized egg.
C.
The nucleus of a sperm cell fuses with the nucleus of the original egg cell, resulting in 48 chromosomes in the fertilized egg.
D.
The nucleus of another egg cell pairs with the nucleus of the original egg cell, resulting in 48 chromosomes in the fertilized egg.

Its C
Explanation:
DNA from 2 parents, 24 from each parent is combined into one with 48 chromosomes. Hopefully, that makes sense and is correct.
What happens during Prophase I? You will need to think about what you learned during mitosis to fully answer the question.
DNA coils into chromosomes
Crossing over
Nuclear Membrane disappears
Chromosomes line up in the middle of the cell
Answer:
Crossing over
Explanation:
Prophase I is the first stage of meiosis I, it is the longest phase of meiosis. Crossing over (also known as recombination) can be defined as the process of exchange of genetic material between non-sister chromatids that occurs during Prophase I. Crossing over represents a critical source of genetic variation in offspring (the other one is the random orientation of the homologous chromosomes pairs). After crossing over, the resulting haploid (n) gametes aren't genetically identical to one another.

What did scientists believe was contributing to the depletion of the ozone layer and why?
CFCs and other halogen-source chemicals in the stratosphere were discovered to deplete the ozone layer.
What is ozone layer depletion?
Ozone depletion is the steady lowering of the Earth's ozone layer in the high atmosphere, which is produced by the discharge of chemical compounds from industry and other human activities that contain gaseous chlorine or bromine.
The ozone layer acts as a buffer against the sun's potentially dangerous ultraviolet rays. The destruction of the ozone layer puts humans in direct contact with dangerous ultraviolet rays, which can lead to a variety of health problems including cancer, cataracts, skin illnesses, and a weakened immune system.

Which of the following best explains the endosymbiosis theory of how eukaryotic cells originated, as shown below? A.Eukaryotic cells developed from mutations in prokaryotic cells
B.Eukaryotic cells developed from organic compounds carried to Earth by debris from space
C.Eukaryotic cells originated from a combination of gases and heat in the atmosphere
D. Eukaryotic cells were originally large prokaryotic cells that absorbed smaller prokaryotic cells
Answer:I’m sure the answer is D
Explanation:
All eukaryotes evolved from prokaryotes and eventually developed into mitochondrial organelles.
The endosymbiotic theory represents that some of the organelles in eukaryotic cells were prokaryotic microbes at some time. As per the endosymbiosis theory the eukaryotic cells were at first large prokaryotic cells that absorbed smaller prokaryotic cells.
What is endosymbiosis?Endosymbiosis is the engulfing of the cell by another one to produce, over time, a coevolved relationship in which none of the cell could survive alone.
It is an evolutionary theory that guides the origin of eukaryotic cells by prokaryotes.
Eukaryotic cells were previously large prokaryotic cells that actually absorbed smaller prokaryotic cells
Thus, the correct option is D.

If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitochondria, because they rely on the ER as an energy source ribosomes, because they receive proteins made by the ER Golgi apparatus, because it packages proteins received from the ER cytoplasm, because it relies on the ER for structural support
Answer:
Golgi apparatus, because it packages proteins received from the ER
Explanation:
The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.
The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.
If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.
Hope that helps.

Answer:
d. Pluripotency markers
Explanation:
Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.

A sample of a meteorite has a density of 23 g/ml. It takes up a volume of 147 ml.
What is the mass of this unknown sample?
Answer:
3,381 grams
Explanation:
The problem can be solved by using the formula for "Density." The formula for density is: Density (ρ) = [tex]\frac{mass}{Volume}[/tex]
Now that we know the formula, we can get the formula for the "mass."
mass = ρ x VolumeThe given density above is 23 g/mL while the given volume is 147 mL. We have the values of the density and volume, thus, it is easy to solve the problem.
Let's solve.
mass = 23 g/mL x 147 mLmass = 3,381 gramsThe mass of the meteorite is 3,381 grams.
