Humans are ____because we must consume other life forms for energy. autotrophs or heterotroph?​

Answer:

the is true

Explanation:

Answer:

The number of electrons does not factor into the overall mass, because their mass is so small.

Explanation:

Because protons and neutrons each have a mass of 1, the mass of an atom is equal to the number of protons and neutrons of that atom.

Answer:

Sexual reproduction provides genetic variation to plants to help them survive in a changing environment.

Explanation:

This would be the most beneficial because more plants would live if the environment changes. Things like finding a mate or more care for there offspring would not be as beneficial because it would not matter as much for the population. I think that having a good population would be the most beneficial.

Sexual reproduction provides genetic variation to plants to help them survive in a changing environment. So the correct option is A.

Sexual reproduction is the process through which two individuals of various sexes combine their genetic material to create new species. In the majority of organisms, reproductive cells called gametes, which mate to create a diploid zygote, have chromosomes in their nuclei that carry the genetic material. The zygote grows into a new person. The most common method of reproduction among living things is sexual reproduction.

A remarkable variety of children, each with a genetic make-up different from that of its parents, may occur from sexual reproduction because it permits the rearranging of genetic material both within and between members of one generation. With the exception of bacteria, all creatures that reproduce sexually share the creation of haploid, uninucleate gametes that combine during fertilization to create diploid, uninucleate zygotes.

The organism's chromosome count is once again decreased by meiosis at a later point in its life cycle in order to create the gametes for the following generation. A majority of forms have a big egg and a minute sperm; the gametes may be equal in size (isogamy) or one may be somewhat larger than the other (anisogamy) (oogamy).

Therefore the correct option is A.

(d) Reginald Punnett

Explanation:

Reginald Punnett, an English geneticist, invented one of the simplest methods for calculating the mathematical probability of inheriting a specific trait. As a result, his method became known as a Punnett Square. It is the most basic graphical method for discovering all possible genotype combinations that may occur in offspring, which were named dihybrid cross and monohybrid cross.

I am joyous to assist you at any time.

Answer:

(d) Reginald Punnett

Explanation:

The representation of the genetic cross can be done by a tool known as Punnet square, which was back then proposed by Reginald Punnet. With this method, this scientist designed a way to measure how probable is a genotype frequency to occurs among the offspring.

So the answer to this question is (d) Reginald Punnet.

Photosynthesis 02.07RITA RIFFI

sunlight is made in to a chemical energy using chlorophyll. Then uses energy to convert co2 and water in to glucose.

Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells.

Here is a step-by-step explanation of the process of photosynthesis:

1. Light Absorption: Chlorophyll, a pigment found in chloroplasts, absorbs sunlight. This light energy is essential for photosynthesis to occur.

2. Conversion of Light Energy: The absorbed light energy is used to power a series of chemical reactions that convert carbon dioxide and water into glucose. This process is called the light-dependent reaction.

3. Production of ATP and NADPH: During the light-dependent reaction, energy is stored in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules act as energy carriers in the next step of photosynthesis.

4. Carbon Fixation: The ATP and NADPH produced in the light-dependent reaction are used in the Calvin cycle, also known as the light-independent reaction or the dark reaction. In this step, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.

5. Release of Oxygen: As a byproduct of photosynthesis, oxygen gas is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans.

Overall, photosynthesis plays a crucial role in the Earth's ecosystem by providing oxygen and producing food for organisms. It is an essential process that sustains life on our planet.

Explanation:

When the membrane is at rest, are the sodium ions more concentrated inside the cell or outside? Where are the potassium ions more concentrated?

Sodium ions are more concentrated outside the cell, and potassium is more concentrated inside.

Sodium ions are more concentrated outside the cell, and potassium is more concentrated inside.

The Importance of Sodium in Biology Sodium ions are found primarily inside human cells, such as Nerve Cells. They are responsible for regulating the flow of water across the membrane. They are required for the transport of sugars and amino acids into the cells of an organism.

Sodium ions are required for the absorption of glucose and amino acids in the small intestine. These molecules are absorbed into the intestinal cells via co-transport channels that are driven by sodium ions.

When the cell membrane is depolarized by a few millivolts, sodium channels activate and inactivate within milliseconds. Influx of sodium ions through the integral membrane proteins comprising the channel depolarizes the membrane.

Since the question does specify what the reference was, I will be referring to different time periods. This question is a bit complicated, and I apologize in advance that this answer will most likely be very long.

There are many things that affect how often these blooms are reported. For example, when people still lived in close colonies, they covered less water mass than now (also because of the population differences). However back then, there probably wasn't as many algae blooms since the environment wasn't as contaminated.

1.) People are more likely to report these sightings when they don't know much on the subject - If you look in the past, humans have been trying to create a reason for everything. When there was a natural disaster, and  they didn't understand it, they said that the divine beings were angry. When people got lucky, they called it fate, or that they had the favor of the god/God/god(s). In the 1700s, the first algae bloom was reported. Of course, they didn't have enough information on the matter and tried to blame it on something. If they saw it again, they might take it as a bad omen and immediately report it. This would increase the percentage of blooms reported that happened around the civilization.

2.) There is a matter of population difference -  In the 1800s, there was approximately one billion people in the world. This population is nearly two times the population in 1700 CE (population: 600 million). Of course, seeing as people started to migrate / spread out across the land, there would be more rivers/bodies of water that are near a civilization. This means that they should, hypothetically, have a larger number of blooms reported. (Note that it is a larger number and not percentage)

3.) Environmental Contamination - As the population rapidly grows, there is a lot more inventions, experiments, technology, and development happening. This also means that the over populated cities such as London would have worse sanitary conditions. (This statement applies only to the before bacteria & other microorganisms were discovered.) Improper disposal of waste would ultimately lead to land and water contamination, which results in more algae blooms appearing. Trash could have also gone to the middle of the ocean. Algae blooms that appear in the middle of the ocean most likely wouldn't get reported, as it isn't located near a civilization. In this case, the percentage would decrease, since the ratio would be off.

Conclusion:

There are many factors that are involved in this complicated problem. It is  also impossible for me to decide which had more algae blooms reported, also because it wasn't specified whether the question was asking for the number or the percentage. Since I cannot properly answer this problem, I listed the major things to think about.

In telophase II, 4 daughter cells are being formed. They are called haploid occur in meiosis II.

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.

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

Secondly Prometaphase I where Spindle fibers attach to the  centromere followed by Metaphase I.

The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.

Telophase I where Spindle fibers disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells. same events are occurred in meiosis II.
