Answer:
1. Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens.
2. Gametes or sex cells are produced in meiosis and they have haploid number of chromosomes. In humans, the haploid number of chromosomes is 23 chromosomes.
Explanation:
Cell differentiation is the process whereby simple generalized cell develop into cell with specialization in function and structures. During the initiation of cell differentiation, transcription factors activate only the genes to be expressed. Some environmental factors that affect gene regulation include diet and nutrition, temperature, oxygen levels, humidity, and the presence of mutagens(factors that cause mutation).
Differentiation occurs in zygotes numerous times resulting in the formation of a fully developed organism. Also in unspecialized cells known as stem cells, differentiation occurs leading to the formation of various cells of the organs and tissues of the body.
2. Meiosis is a type of cell division in which gametes or sex cells are produced. A single cell divides twice producing daughter cells with half the number of chromosomes present in the parent cell. In humans, the chromosome number is 46. After, meiosis, the haploid number of chromosomes produced is 23.
Explain how roots hair cells use osmosis to take up water.
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.

What happens when magma cools during the rock cycle? Igneous rock is formed. Metamorphic rock is melted. Sediments form sedimentary rock. Metamorphic rock forms sediments.
Answer: igneous rock is formed
Explanation:
When magma cools down during the rock cycle then igneous rock is formed. Thus, the correct option is A.
What are Igneous rocks?Igneous rock is one of the three main rock types, while the other being sedimentary and metamorphic rocks. Igneous rocks are the rocks formed through the cooling and solidification of magma or lava from volcano. The magma can be derived from partial melts of existing rocks in either a planet's mantle or the crust.
Lava from the volcano cools to form volcanic rock as well as volcanic glass. This magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma then solidifies in the atmosphere to form volcanic rock called as tephra. In the atmosphere, tephra is more often called as volcanic ash.
Therefore, the correct option is A.

Answer:
Explanation:
The black trait is a recessive trait because it only shows up in 3 people in that is rare. It also only occurs in either male or female looking at the shapes. The first part may be wrong but I believe that this is a Autosomal trait because it isn't occuring in every single person meaning it is a mutation.

what process causes water to move in and out of the central vacuole? explain
Answer:
In plant cells, osmotic pressure can cause changes in the size of the central vacuole, which shrinks or swells as water moves into or out of the cell.
Explanation:
Hope this helped, Have a Great Day/Night!!
Answer:
Function of the Central Vacuole
Turgor pressure changes in a cell due to osmosis, which is the diffusion of water into or out of the cell. When a plant cell is in a hypotonic solution, there is a higher concentration of water molecules outside the cell than inside, and water will flow into the cell.

Explanation:
Cells spend very little of their life performing mitosis. Most of a cell’s life cycle is spent in interphase. Interphase is made up of the first growth phase, the synthesis phase, and the second growth phase. The synthesis phase is characterized by -
The division of cytoplasm
Cell division
Replication of mitochondria and other organelles
DNA replication
Answer:
DNA replication
Explanation:
Synthesis is the stage characterized by DNA replication. It is after the G1 phase
Most of the cell's time is spent in the interphase. The first growth phase comes first, then the synthesis phase, and finally the second growth phase. In the synthesis phase, DNA replication occurs. So the last option is correct.
What is interphase in a cell cycle?
The interphase is the preparatory phase of the cell before going into the division phase (M phase). The first phase is the G1 phase, or first growth phase, in which the cell grows in size. Then the cell enters the synthesis phase, or S phase, where the cell's genetic material, which is DNA, is replicated.
A single DNA molecule duplicates itself, but the two DNA molecules are linked by a single centromere. In synthesis phase the centrosome replicates too, making two centrosomes. Then the cell enters the second growth phase, or G2 phase. Here the cell again grows for the division.
Hence, in the synthesis phase, DNA replication occurs. The last one is correct.

Explanation:
An agricultural biologist was evaluating two newly developed varieties of wheat as potential crops. In an experiment, seedlings were germinated on moist paper towels at 20ºC for 48 hours. Oxygen consumption of the two-day-old seedlings was measured at different temperatures. The data are shown in the graph below. In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxidized to NAD+. Predict the most likely effect of the chemical on metabolism and oxygen consumption of the treated seedlings. Explain your prediction.
Answer:
The definition is listed in the clarification segment below, and according to the present circumstances.
Explanation:
It undergoes different morphological as well as biochemical modifications mostly during germination. Product contains nutrients and even some hydrolases such as energy, carbohydrates. Owing to the availability of phytic compounds, the seed coat seems to be very durable in nature. Hydrolytic enzymes launch their function by consuming oxygen throughout order to remove this hard coating. In several other processes, including the electron transport system as well as the Kreb process, oxygen also becomes necessary.
The initial phase of germinating seeds requires anaerobic environments where even the enzymes dehydrogenase can function. The subsequent dehydrogenase enzyme brings the electron throughout the electron transport system from either the base to oxygen. Unless the oxygen frequency is compared with varieties A and B, it can be seen through the analysis that variety B actually absorbed more oxygen. Oxygen intake rates are also depending upon period.The impact of temperature mostly on absorption of oxygen seems to be present. Shift the supply at low temperatures have a low intake of oxygen, while varieties grown over extreme temperatures use much more oxygen. The metabolism of such a seedling is influenced by temperature. Metabolically active young plants display a larger intake of oxygen.Name the plant cell organelle where photosynthesis occurs

Describe the processes of transcription and translation in your own words, based on what you have observed in the Gizmo.
Terms to use in your answer: amino acid, anticodon, codon, gene, messenger RNA, nucleotide, ribosome, RNA, RNA polymerase, transcription, transfer RNA, translation.
The explanation of transcription and translation using the mentioned key words is as follows:
TRANSCRIPTION AND TRANSLATION
Transcription is the process whereby a gene in a DNA template is used to synthesize a messenger RNA (mRNA) molecule in the nucleus of the cell. This process of transcription occurs with the aid of an enzyme called rna polymerase, which adds the nucleotides complementary to the one it reads in the gene to the growing mRNA strand. Translation, on the other hand, is the second process of gene expression involving the synthesis of proteins from the mRNA sequence. This process occurs in the ribosome where a group of three nucleotides in the mRNA called codon is read by another group of complementary nucleotide in the transfer RNA (tRNA) called anticodon. The tRNA then carries amino acids corresponding to what is read in the codon to the growing polypeptide chain.Learn more about transcription and translation at: https://brainly.com/question/23259013?referrer=searchResults
