pls help me I need a answer asap
Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .

Your skin is constantly producing new cells through cell division. How does this happen? During interphase, how does a cell prepare for division? Describe cell division, including the processes of mitosis and cytokinesis. Be sure to describe the mitotic steps.
Answer:
Answer:
Explanation:
Cell division is the process whereby a parent cell finish up into two daughter cells. they are two types of cell division
mitosismeiosismitosis is a process whereby a parent cell finish up and produces two daughter cells having the same number of chromosomes
stages of mitosis
Interphase: In this stage , nothing really happens in the cell, resting stage of the cellprophase: in this stage , the chromatins condenses into chromosomes, the nuclear membrane disappear and the spindle fibre radiates
metaphase: in this stage , the chromosomes align in the middle and meet at the equatoranaphase: the chromosomes split at the centromere and move to the opposite polestelophase: the cell splits, and the spindle fibre disappears cytokinesis: the cell produces two daughter cellsAfter a long soccer practice, Jack felt his pulse increase.

water?
Pls help meee I will mark ❤️❤️❤️❤️
Answer: 1. Oxygen is used by cells to make energy.
2. Lungs, pharynx, larynx, trachea, bronchi, and diaphragm.
3. Blood carries oxygenated blood to the body and deoxygenated blood back to the lungs.
4. Increased amount of carbon dioxide lowers the pH of blood. Brain sends signal to the diaphragm to increase activity to get rid of carbon dioxide.
5. In the alveoli, oxygen and carbon dioxide move from high concentration to low concentration (this is also known as diffusion)

Read the following passage on Hox genes. Using the information presented, write a short passage to support the claim that many Hox genes are regulatory genes.
The genome of an organism can be many millions of base pairs long. Genes are regions of the chromosome that code for protein products. They are scattered throughout the chromosome with little logical reason for their placement. There is an exception to this disorder—Hox genes, which are a family of genes that produce transcription factors. Hox genes are found in most eukaryotes. They are clustered together in the genome and always found in a particular order. The genes are in the same order as the characteristics are found along the body axis in the organism itself. These genes specify segment placement, such as whether a segment will form part of the head, thorax, or abdomen. For example, Hox genes related to structures in the head of an organism are found first in the Hox cluster.
Hox genes have been studied in fruit flies. A cluster of 8 Hox genes are activated very early in development, laying out the segmented body plan of the head, thorax, and abdomen. There are very clear boundary lines of expression for each Hox gene. In fact, forcing embryonic Hox gene expression in a wrong part of the body can cause another region’s body parts to develop. Scientists created a fly that had legs where its antennae should be through induced Hox expression!
Answer:
hox genes are a subset of regulatory genes that encode transcription factors and they are important for embryonic development. they are activated by a cascade of regulatory genes and the proteins encoded by the early genes regulate expressions of later genes
Explanation:
The orderly arrangement and clear boundary lines of expression for each Hox gene suggest that many Hox genes are regulatory genes. Hox genes produce transcription factors that control the expression of other genes, regulating the developmental processes that determine segment placement and body plan.
Describe more about Hox genes ?The placement of Hox genes in a particular order along the chromosome is also indicative of their regulatory function. Hox genes are clustered together and in the same order as the body axis of the organism, suggesting that their arrangement is not random but rather a functional design.
Additionally, the ability to induce Hox gene expression in the wrong part of the body and cause the development of body parts from a different region of the organism further supports the regulatory role of Hox genes.
This shows that Hox genes have the ability to control the fate of cells and determine the formation of body structures. Therefore, it is clear that many Hox genes are regulatory genes that play a critical role in controlling the complex developmental processes of organisms.
Hox genes are also known for their role in evolutionary biology. Changes in the expression pattern or function of Hox genes can result in significant changes in body plan and morphology, leading to the development of new structures and functions.
For example, it is believed that the evolution of the arthropod body plan and the development of the jointed appendages in insects was due to changes in the expression of Hox genes. Similarly, changes in the Hox gene expression pattern have also been linked to the evolution of the vertebrate body plan and the development of the vertebrate limb.
Moreover, Hox genes have been linked to several human genetic disorders. Mutations in Hox genes can cause developmental abnormalities such as synpolydactyly, a condition where fingers and toes are fused together, or polydactyly, where there are extra fingers or toes. Mutations in Hox genes have also been associated with some forms of cancer, such as leukemia.
In summary, Hox genes are a family of regulatory genes that play a critical role in controlling the complex developmental processes of organisms. They are known for their role in determining segment placement and body plan and have been linked to evolutionary changes, developmental abnormalities, and some forms of cancer.

What is a karyotype and how do they help scientists
Answer:Karyotyping is a laboratory procedure that allows your doctor to examine your set of chromosomes. “Karyotype” also refers to the actual collection of chromosomes being examined. Examining chromosomes through karyotyping allows your doctor to determine whether there are any abnormalities or structural problems within the chromosomes.

How can we edit bacterial genome?
Help!
Answer:
Explanation:
Restriction enzymes refer to enzymes that is produced by a bacteria which has the ability to cleaves DNA property to a specific restriction sequence site within the molecule.
Restriction enzyme is use to cut DNA into smaller fragments by preventing the replication of the phage DNA .
Restriction enzyme is use when there is infection or foreign materials that intrude into a bacterium,the bacterium uses it to defend itself against infections that might be cause by viruses, pathogens e.t.c.
Bacteria genome can be edited using CRISPR method. It is done with recombineering, which is a technique that uses phage recombination method to enhance homologous recombination of DNA fragments.

How is water formed during the electron transport chain
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.
Many freshwater plants have adapted to low carbon and light levels by adapting what feature?
Group of answer choices
Carnivorous plants
No need for carbon dioxide
Camouflage
Floating leaves
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water. They are therefore a common component of wetlands.
