Answer: D
Explanation:
Chromosomes are the inherited unit of the organism which transfers the parental gene to the offspring.
The diploid is the paired chromosome quantity present in the cell that originates from each parent.
The correct answer is:
Option D. 64
This can be explained as:
The diploid (2n) number of chromosomes = 12Haploid (n) number of chromosome = 6The possible number of chromosome pairs is given by 2ⁿ. Where n = a haploid number of chromosomes.So, the possible combinations of chromosomes that could be found in the gametes with no crossing over will be:
= 2⁶
= 64
Therefore, 64 possible combinations of chromosomes can be present.

What two groups are represented in archaeopteryx?
Please help
Answer:
The species of Archaeopteryx is lithographica and siemensii
Explanation:
Fun fact: Archaeopteryx is a combination of two ancient Greek words: archaīos, meaning "ancient," and ptéryx, meaning "feather" or "wing."
Archaeopteryx has long been thought to be the earliest known bird and a transitional form between birds and reptiles.
What are Archaeopteryx?Many consider Archaeopteryx, which lived approximately 150 million years ago, to be the first bird.
It is actually a transitional species between the birds we see in our backyards and predatory dinosaurs like Deinonychus.
Many features of Archaeopteryx, such as teeth and a long tail, indicate that it evolved from comparatively tiny carnivorous dinosaurs.
It also has a wishbone, a breastbone, hollow thin-walled bones, air sacs in the backbones, and feathers, as do nonavian coelurosaurian relatives of birds.
Archaeopteryx was thought to be the first recognized bird and a transitional form between birds and reptiles for a long time.
Thus, the two groups that are represented in archaeopteryx are birds and reptiles.

What differs Flood from Flash Flood then? Explain your answer concisely.
Floods and flash flooding Now is the time to determine your area's flood risk. ... Flash floods have a rapid hydrological response in catchments with short lag times, ... Two different types of flood hazard assessment methods were tested: (i) a ... elongation ratio and roughness index can be used to explain the flash flood types.
Answer:
Flooding is an overflowing of water onto land that is normally dry. Floods can happen during heavy rains, when ocean waves come on shore, when snow melts quickly, or when dams or levees break. Damaging flooding may happen with only a few inches of water, or it may cover a house to the rooftop. A flash flood is = A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours. Flash floods are usually characterized by raging torrents after heavy rains that rip through river beds, urban streets, or mountain canyons sweeping everything before them.

Is using fossil fuels in generating electricity better or using renewable energy? why?
Answer:
Explanation:
Using renewable energy will always be better than fossil fuels.
This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.
Which statement best compares the amount of fossil fuels formed each year to the amount used each year?
The amount of fossil fuels formed is exactly the same as the amount used.
The amount of fossil fuels formed is approximately the same as the amount used.
The amount of fossil fuels formed is much less than the amount used.
The amount of fossil fuels formed is greater than the amount used.

what are the different ways of storing tools and equipment safe
answer is included in the picture below.
Answer:
Step 1
Delegate a portion of your garage, shed or basement closet as a place to store tools. Clean out the junk and clutter and make a space only for tools. Figure out how much space is needed for the amount of tools you have. Sweep away cobwebs, dirt and other foreign matter. Get a shelving unit and store chemicals, liquids and paint substances out of the reach of children and pets.
Step 2
Find the parts. Locate cords, bits, nails and screws and organize them. Allocate plastic bins to store smaller household tools. If you have a large tool collection, organize by type for easy location. Keep the parts for each specific tool close by.
Step 3
Clean out dirt and debris from tools. Oil power tools to lubricate moving parts. Repair loose handles and clean out oil or other fluids used to power the tool. Sharpen blades and replace worn out parts.
Step 4
Set up racks. Mount commercially available racks along the wall of your garage or storage area to hang garden tools, cords and other equipment. Screw racks into the wall with screws recommended by the manufacturer and a power drill. Wind long cords in a loop and hang from rack. Place tools on racks by the handle. Draw the outline of the tool with a permanent marker to identify its place, or use labels to mark the location.
Step 5
Create a library. For tools and appliances that have various functions, designate a library area or bin within the storage space for user manuals and warranty sheets. Store the booklets alphabetically and in a dry area. Type up a sheet listing all of the books to create simple table of contents.

As nutrients increase, the number of life-forms increases.Thus, the correct option for this question is A.
What do you mean by Estuary?An Estuary may be defined as a type of ecotone that signifies the transitional zone of two different ecosystems which include the freshwater river ecosystem and the marine water ocean ecosystem.
In this ecotone, the characteristics of both ecosystems are present. Hence, it has a high biodiversity as compared to both ecosystems individually. This region shows maximum diversity and is thus known as the edge effect.
This illustrates that when nutrients in the ecotone increase, the number of life forms i.e. biodiversity increases.
Therefore, the correct option for this question is A.

What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
The body would synthesize the amino acids.
Muscle growth and repair would be limited.
Stored protein would break down.
The formation of proteins would increase.
Answer:
Muscle growth and repair would be limited
Explanation:
plz give me brainiest
Essential amino acids are the vital nutrients required by the body. The deficiency of the amino acids in the diet will limit the growth and repair of the muscles. Thus, option B is correct.
What are the essential amino acids?Essential amino acids are the amino acids that are not synthesized by the body and instead are taken from external sources in the diet. Some of the essential amino acids include histidine, lysine, valine, phenylalanine, etc.
The essential amino acids improve the musculoskeletal and the immune system along with stimulating the growth and production of hormones.
If the diet lacks the essential amino acids then the repair mechanism and the growth of the body will be limited as they are not synthesized by the body.
Therefore, the absence of essential amino acids limits muscular growth and repair.

How has the poison changed the concentration of pyruvate, NADH and intermembrane H+ in Jared’s cells?
Answer:
no change, increase, decrease
Explanation:
I just did it
Cyanide interrupts the electron transporter chain. Pyruvate concentration DOES NOT CHANGE. NADH concentration INCREASES in the matrix, and H+ concentration DECREASES in the intermembrane space.
-----------------------------------
Let us firts make a quick revision of aerobic respiration.
Through cellular respiration, cells degrade organic compounds and produce energy.
Aerobic respiration takes place in three steps:
1) Glycolysis is the first step of cellular respiration. It occurs in the cytoplasm, and its final product is Pyruvate.
2) The Krebs cycle takes place in the mitochondria matrix.
3) The electron transporter chain is placed in the internal mitochondrial membrane.
*******************
We already know that cyanide affects the electron transporter chain. So, let us focus on its functioning under normal conditions and under the cyanide effect.
⇒ Under normal conditions,
• ATP is produced at the end of the electron transporter chain.
• The electron transporter chain constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.
• Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.
• Cytochrome oxidase (P450) is one of the enzymes involved in this electron transport.
• NADH and FADH2 provide electrons to the chain.
• While electrons move along the chain, complexes I, III, and IV pump protons to the intermembrane space.
• At the end of the chain, water molecules and ATP are produced.
⇒ Under cyanide effect,
• Ion cyanide inhibits cellular respiration.
• Cyanide binds to the ferric ion of cytochrome oxidase.
• Cyanide-ferric binding inactivates the enzyme and blocks electron transference.
• The chain is interrupted. Hence,
NADH and FADH2 stop providing electrons, complexes I, II, and IV stop pumping protons to the intermembrane space, there is no oxygen consumption and no ATP production.• Since muscles do not get to have ATP as a source of energy, they weaken.
• The interruption of the electron transporter chain produces an anaerobic state that could be culminating.
*************************
Now, let us answer the question
Pyruvate concentration ⇒ NO CHANGESince Pyruvate is produced in the cytoplasm, it is not affected by cyanide. Remember that cyanide only affects the electron transporter chain.
NADH concentration ⇒ INCREASE
Since NADH provides electrons to the chain, and Cyanide interrupts electron transport, there is an accumulation of NADH molecules in the matrix.
Intermembrane H+ concentration ⇒ DECREASE
Since the electron transporter chain is interrupted, no electrons are being carried, and no protons are being pumped to the intermembrane space.

B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
A) it is moving down the concentration gradient
Explanation:
Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.
