Explanation:

Answer:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Explanation:

The nuclear division that forms haploid cells, which is called meiosis, is related to mitosis. As you have learned, mitosis is the part of a cell reproduction cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus.

Answer:

In general, mitosis (division of the nucleus) is preceded by the S stage of interphase (during which the DNA is replicated) and is often followed by telophase and cytokinesis; which divides the cytoplasm, organelles and cell membrane of one cell into two new cells containing roughly equal shares of these cellular components.

Explanation:

The different stages of Mitosis all together define the mitotic (M) phase of an animal cell cycle—the division of the mother cell into two genetically identical daughter cells.Meiosis results in four haploid daughter cells by undergoing one round of DNA replication followed by two divisions. Homologous chromosomes are separated in the first division.

Answer:             Water pollution also affects the ecosystem – it can cause a phenomenon called eutrophication. This can cause fish and other aquatic organisms to die. Toxic elements dissolved in water can make their way to humans through fish or other aquatic organisms.

A disorder that is a result of shortage of proteins in children is Kwashiorkor

Explanation:

Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)

Hopefully this helps.

Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.

Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.

Other terms for kwashiorkor include:

protein malnutrition

malignant malnutrition

protein-calorie malnutrition

Answer : Yellow

Explanation : Because purebred plants have lighter colored dominence .

Answer: Anterograde direction.

Explanation:

Choline acetyltransferase is an enzyme made in the body of a neuron and that needs to be transferred to the axon terminal to perform its function. Its function is to bind acetyl-CoA to choline to form the neurotransmitter acetylcholine.

The movement toward the cell body is called retrograde transport and the movement toward the synapse is called anterograde transport. So, since it is produced in the body of the cell and it has to go to the axon terminals, the choline acetyltransferase is transported in the anterograde direction.  

This type of transport is responsible for the movement of organelles such as mitochondria, lipids, synaptic vesicles, proteins from a neuron cell body through the cytoplasm of its axon called the axoplasm. Because axons can sometimes be meters long, neurons cannot rely on diffusion to carry products to the end of their axons. Dynein is a motor protein involved in this retrograde axonal transport. Its light chains bind cargo, and its globular head regions bind the microtubule, "moving forward" along it.

Answer:

The correct answer is - Eubacteria.

Explanation:

Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:

Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.

Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.

Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.

Answer:

D the answer

Explanation:

Answer:

- Late Pleistocene hominins found only in Europe, Western Asia, and Central Asia; the Shanidar site belongs to this group: Neandertals

- Middle Pleistocene hominin; found in Africa, Asia, Europe; shows a mixture of features from previous and later hominins: Homo_heidelbergensis

Explanation:

Neandertals represent an extinct hominid lineage and the closest evolutionary relatives of humans. Neandertals lived in Europe, Central Asia, the Middle East and western Siberia. This group of extinct hominids appeared around 130,000 years ago until their extinction, approx. 40,000 years ago. On the other hand, Homo_heidelbergensis is an extinct group of Homo_Hominids who lived during the Middle Pleistocene, a time period spanning 780,000-120,000 years ago. Homo_heidelbergensis is considered the most recent common ancestor between H. sapiens (modern humans) and Neanderthals. This species (Homo_heidelbergensis) combined primitive features (e.g., a wide face, and thick arching brow ridges) with modern features (e.g., a large brain capacity).

1. blueprints.

2. cells use DNA as their design plans

Explanation:

Blueprint is a representative drawing of an engineering plan that helps in understanding how and where the desired to construct on the house. It helps in communicating what work should be done in the house. It helps in visualizing how the end product should be.

In cells, the design plan is DNA that encodes all the information in a specific nitrogenous base sequence in order to produce specific functions and produce all the proteins

Answer:

There is no diagram but the cell division happens in stages. PMAT is a way to remember them. prophase, metaphase, anaphase, and telophase. This all takes place in Mitosis. Mitosis is the division of cells to make more *identical* cells, (skin cells, stomach cells). But Miosis is the making and division of sperm cells *not Identical* (sperm, and egg cells) are made in this phase.

Answer:

Metabolic pathways in monarch butterflies are as follows:

Explanation:

They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.

They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.

During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose.  The conversion of fat also releases little water which help them to survive during winter.

1) Glycolysis:

2. Kreb's Cycle:

The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.

3. Oxidative Phosphorylation:

The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.

When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.

This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.

The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.

Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.

Answer:

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the white cells).

Answer:

E

Explanation:

Red blood cells, most white blood cells, and platelets are produced in the bone marrow, the soft fatty tissue inside bone cavities. Two types of white blood cells, T and B cells (lymphocytes), are also produced in the lymph nodes and spleen, and T cells are produced and mature in the thymus gland.

Answer:

What are the necessary components required to start the transcription of a gene?

Explanation:

Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.

After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.

The digestion of lipids and protein begin in the dudoneum of small intestine.

Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.

The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.
