Explanation:
Which one of the following is the name for the way cells divide in asexual reproduction?
Twins
Mitosis
Meiosis
Generation Square
Answer:
Mitosis
Explanation:
When a eukaryotic cell divides asexually, the nucleus and its genetic contents must divide too, in a process called mitosis. Both haploid (n) and diploid (2n) cells can divide asexually, at which time their nuclei divide mitotically.
Each "word" in the mRNA language consists of how many letters?
Answer:
3 letters
Explanation:
The "letters" of the alphabet are grouped into "words" of three letters each. On the mRNA molecule each "word" of three letters is called a codon. a single codon specifies, or "codes for", a single amino acid.
Earth is composed of layers of material with different properties. Which
of the following is most likely to contain material that is in constant
motion?
So
Answer:
mantle
Explanation:
A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.

How are tropical plants such as bromeliads adapted to the biome in which they live?
O A. They grow from tree branches rather than the forest floor, which helps them to absorb more sunlight.
OB. They have long, thick roots, which helps them to gather the nutrients that are found deep within the soil.
O C. They have hollow leaves and stems for storing water, which helps them to survive long periods with little rainfall.
O D. They lose their leaves during the winter, which helps them to save energy when the temperature falls and prevents the buildup of
snow.

Describe how restriction enzymes and ligase enzymes are used to make the plasmids that are introduced to bacteria cells during transformation. Include the words sticky ends and complementary in your response.
Answer:
DNA restriction enzymes cut the DNA molecule, while DNA ligases join the resulting DNA fragments
Explanation:
Transformation is a naturally occurring process by which bacteria incorporate exogenous genetic material from their surrounding environment. This process (transformation) is used for DNA cloning via plasmid vectors. In DNA cloning, transformation occurs after restriction enzymes cut the DNA at specific sequences named palindromic sequences (i.e, sequences that can be read the same in opposite direction). Restriction enzymes can generate sticky-ends, where enzymes make staggered cuts in the two strands (e.g., BamH), or blunt ends, where the resulting strands are of the same length (e.g., HaeIII). In general, sticky-end enzymes are more useful because they generate a 3' overhang in one molecule and a complementary 5' overhang in the other, increasing the yield and specificity of ligation. During ligation, a DNA ligase is used to join both DNA strands by forming phosphodiester bonds in the plasmid. Following transformation, bacteria can be selected on antibiotic plates.
What are similarities about Early earth and Modern earth
Answer:
Crust, mantle and core.
Water availability.
Volcanic eruptions.
Explanation:
The main similarities about Early earth and Modern earth is their layers of soil such as crust, mantle and core means that the both Early earth and Modern earth are made up of these three layers. At that time water is present in huge amount while on the other hand, in Modern earth water is also present in large amount as compared to land. Volcanic eruptions occurs in both early and Modern earth.

In the Punnett square below what would be the genotype for the organism represented by box 2?
1.) bbss
2.) BbSs
3.) bbSs
4.)Bbss
Answer:
bbss
Explanation:
mitochondria is the powerhouse of a cell
The genotype for the organism is represented by box 2 - 1.) bbss.
Punnett square is a way to find the genotype of any trait either monohybrid or more than one allele. To predict the outcome of breeding experiments where one trait with two boxes and two traits are being followed and the Punnett square is larger, with sixteen boxes.
Each side has gametes, representing alleles they have, produced by each parent.Each box shows the zygote that has a genotype combination of the gametes.for instance, here bs is fused with bs which form the zygote that contains the genotype bsbs.Thus, The genotype for the organism is represented by box 2 - 1.) bbss.

phase? Choose all that apply.
We see more of the lighted side of the moon.
We see less of the lighted side of the moon.
The time it takes to go from new moon to full moon is 2 weeks.
The time it takes to go from the new moon to full moon is 4 veeks.
Answer:
We see more of the lighted side of the moon because it is growing, so we see more
The time it takes to go from new moon to full moon is 2 weeks, because it takes a whole month (4 weeks) to go from new moon to full moon to new moon

The respiratory system brings in _________ and the digestive system breaks down _____________ so that both substances are available to cells to make __________.
Answer:
Oxygen; food; adenosine triphosphate (ATP).
Explanation:
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).
All living organisms such as plants and animals require energy to function properly (life activities). The cell organelle where energy from nutrients are released is generally referred to as mitochondria. Animals and plants retrieve energy using mitochondria to do cellular respiration because they typically act like a digestive system by taking in nutrients, breaking them down and obtaining energy rich molecules for cell-life activities.
This ultimately implies that, 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.
Generally, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe (respiratory system) while glucose is absorbed by the body when they eat (digestive system).
Hence, the respiratory system brings in oxygen and the digestive system breaks down food so that both substances are available to cells to make adenosine triphosphate (ATP).

What would happen if cytokinesis did not occur?
Answer:
Cytokinesis takes place in both meiosis and mitosis and performs the separation of he cell in half and form one nucleus into each daughter cell.
If cytokinesis did not happen, it will from multinucleated cells which means that their will be multiple nuclei in single cell and cell will not get separate in half, and no new daughter cells will form.

What is number of ATP molecules produced per molecule of glucose when Pyruvate is used to produce NADH, ATP, and FADH2
Answer:
2 ATP molecules.
Explanation:
This question is describing KREB'S CYCLE, which is the second stage of aerobic cellular respiration that occurs in the mitochondrion. In the Kreb's cycle, also known as tricarboxylic acid cycle, pyruvic acid (product of glycolysis) is oxidized to produce NADH, FADH2, ATP and CO2 as products.
In a nutshell, per glucose molecule that begins the respiration process (glycolysis), 2 molecules of ATP are produced alongside 3 NADH and 1 FADH2 molecules in the Krebs cycle. Note that, the electron carriers (NADH and FADH2) are used in the electron transport chain.

Why must cells divide to stay small or change shape to reduce volume?
O To diffuse substances from an area of higher to lower concentration
To ensure the cell is able to obtain nutrients or remove wastes.
To reduce surface area of the cell for quick movement.
O To move water molecules from areas of high to low pressure
Answer:
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Explanation:
Answer:
To ensure the cell is able to obtain nutrients or remove wastes.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume That is why cells are so small.
