Answer:

liver cell

Explanation:

The liver parenchyma is primarily comprised of hepatocytes. Hepatocytes are polygonal epithelial cells with abundant eosinophilic, granular cytoplasm and large, centrally located round nuclei. Hepatocyte nuclei often contain a prominent nucleolus. Binucleated hepatocytes (= containing two nuclei) are not uncommon.

Answer:

Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.

Answer:

Genotype

Explanation:

A plant with wrinkled seeds would have the following genotype: (rr).

Answer:

Cellular respiration, which generates ATP in your cells, requires oxygen to take place, also, it generates CO2 as a waste product. The respiratory system allows oxygen to diffuse into your blood, and carbon dioxide to diffuse out. The blood then carries the oxygen to the cells, so cellular respiration to continue. When the blood reaches the cells, it also takes the carbon dioxide out of the cells, and carries it to the lungs to get rid of it.

Answer:

It can easily remove dirt.

Explanation:

When dirt is present on the hard surface such as car or machines so it can be cleaned by using hard cloth because the dirt attached tightly to the surface which can only be removed from that surface with the help of using hard cloth. Hard cloth has rough surface which easily remove the dirt from the surface as compared to the light cloth so that's why hard cloth is used to remove dirt from the surface.

Answer:

A system that biologically digests organic material

A biodigester is a system which biologically digest organic materials..

Explanation:

They are helpful in mate selection rather than being mostly beneficial to survival

In order to replicate, DNA needs the help of a lot of enzymes and primers (helicase, DNA polymerase, RNA primer, ligase, etc) It is also SUPER important that there is a template for the DNA to replicate off of so that the genetic info is passed on from one generation to the next without any changes or damage to the DNA

Answer:the answers is B

Explanation:

Because reproduction occurs between homologous a chromosome

During meiosis, a process known as crossing over occurs. Genetic information is removed from both chromosomes.

Meiosis is the process  where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.

Humans have 46 chromosomes in every cell,  where 23 chromosomes t came from one of our parents and 23 very similar chromosomes that came from the other parents.

Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibres appear.

Secondly Prometaphase I where Spindle fibres attach to the  centromere followed by Metaphase I where The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibres disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells.

Question:

I failed to find the options, but I will post the way by which you can construct Punnett squares.

Answer and Explanation:

First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.

Then, by using a simple square, you will make the crosses. This is:

In the attached files, you will find an example of the cross between two pure-breeding plants.

Answer: Land, Water,Urbanization, and smog and acid rain.

Explanation:

Smog and acid rain are produced through similar sources, primarily vehicle and industry emissions. Though both result from human-caused air pollutants, there are chemical distinctions between the two. Though there are regulations in effect to reduce both types of pollution, they remain a threat to both human health and the environment.Smog Causes A combination of three components -- nitrogen oxides, volatile organic compounds (VOCs) and sunlight -- causes smog. Nitrogen dioxide interacts with sunlight to create nitrogen oxide and a free oxygen molecule. This interaction produces ozone, which typically turns back into nitrogen dioxide, and the cycle repeats. The addition of VOCs interrupts the cycle, however. VOCs are produced by various sources, such as paint, cleaning products and refrigerants. The VOCs prevent the breakdown of ozone, allowing it to gather near the surface of the Earth, where even more nitric oxides are produced by vehicle and industry emissions, creating the dense smog seen in large cities such as Los Angeles and Beijing.Smog Hazards The presence of ozone in the form of smog can have several negative health effects. Respiratory systems can be irritated, reducing overall lung function and triggering asthma attacks. Evidence reported by the Environmental Protection Agency also suggests exposure to ozone reduces immune system responses, especially in the lungs. These effects subside over time, but little is known about the long-term effects of repeated exposure. Vegetation also suffers from smog, as plants that take up too much ozone can be damaged in ways such as discoloration and a loss of leaves that cuts photosynthesis efficiency by up to 50 percent.

Answer:

pollution I took the quiz

Answer:

kingdom plantae

Explanation:

members of this kingdom have a cell wall that gives their cells a box like structure

Organisms that belong to Kingdom Monera, Protista, Fungi, and Plantae all have cell walls.

The cell wall is the outermost covering of the cell which provides the cell with a rigid structure and protects it from the outside environment. It is present outside the plasma membrane.

The composition of the cell wall differs in different organisms. The cell wall in plants is composed of cellulose, hemicellulose, and pectin. In algae, the cell wall is composed of glycoproteins and polysaccharides.

Bacteria that belong to Kingdom Monera possess a cell wall composed of peptidoglycan while the organisms of Kingdom Fungi have a cell wall made up of chitin.

Therefore, organisms of the four kingdoms Monera, Protista, Fungi, and Plantae all possess a cell wall.

Answer:  A group of individuals not chewing gum.

Explanation: A control group is what you are going to compare the experimental group to. Since you are experimenting on if gum will cause someone to perform better on tests you will compare their score to the group that's not chewing gum.

C. Not Likely to form any bonds

Explanation:

Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not  form bonds, generally speaking.

Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.

Answer:

Protiens

Explanation:

Amino Acids are protiens, so after the tRNA join to the MRNA peptide bonds are formed creating long protien chains which are protiens.

Answer:

Salinidad, acidez, oxígeno, niveles de luz y temperatura.

Explicación:

Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.
