Answer:

Explanation:

Energy is transferred through an ecosystem in steps, making up a food chain or a food web. At the bottom of the chain are the primary producers, which absorb sunlight and use the light energy to convert carbon dioxide and water into carbohydrates (long chains of sugar molecules) and eventually into other biochemical molecules, by photosynthesis.

The primary producers support the consumers—organisms that ingest other organisms as their food source. Finally, decomposers feed on decaying organic matter, from all levels of the web. Decomposers are largely microscopic organisms (microorganisms) and bacteria.

The food web is really an energy flow system, tracing the path of solar energy through the ecosystem. Solar energy is absorbed by the primary producers and stored in the chemical products of photosynthesis. As these organisms are eaten and digested by consumers, chemical energy is released. This chemical energy is used to power new biochemical reactions, which again produce stored chemical energy in the consumers' bodies.

Energy is lost at each level in the food web through respiration. You can think of this lost energy as fuel burned to keep the organism operating. Energy expended in respiration is ultimately lost as waste heat and cannot be stored for use by other organisms higher up in the food chain. This means that, generally, both the numbers of organisms and their total amount of living tissue must decrease greatly up the food chain. In general, only 10 to 50 percent of the energy stored in organic matter at one level can be passed up the chain to the next level. Normally, there are about four levels of consumers.

A food chain or a food web is made up of the stages through which energy is moved across an ecosystem. The primary producers are found at the bottom of the food chain.

By photosynthesis, they transform carbon dioxide and water into carbohydrates (long chains of sugar molecules) and ultimately into other biological compounds.

The consumers are organisms that consume other organisms as food—are supported by the primary producers. Decomposers, who feed on decaying organic materials from all tiers of the web, are the last group. The majority of decomposers are bacteria and tiny organisms.

The food web actually follows the route of solar energy through the environment and is a system of energy flow.

Therefore, A food chain or a food web is made up of the stages through which energy is moved across an ecosystem. The primary producers are found at the bottom of the food chain.

Answer:

Has more offspring that have the ability to survive and reproduce themselves.

Explanation:

Evolution fitness can be defined as a characteristic or quality possessed by living organisms and determines their adaptability, as well as level of success in terms of reproduction i.e giving birth to offsprings.

Hence, if you say that a ground squirrel has greater evolutionary fitness than another ground squirrel in the same population, you mean that the animal has more offspring that have the ability to survive and reproduce themselves.

Answer:

26%

Explanation:

if cytosine makes up 24%, then guanine also makes up 24%.

add these to get 48%.

subtract that from 100% to get a remaining 52%

then split the 52% between adenine and thymine to tell you that 26% is thymine

The percent of  the nucleotides in this sample will be thymine should be considered is the 26%.

Since

Cytosine makes up 24% of the nucleotides

So here the guanine should be 24%

Now if we add together should be

= 24% + 24%

= 48%

Now the remaining should be

= 100 - 48%

= 52%

Now here we half the 52% so it comes 26%

Therefore, the option b is correct.

.Answer: if the image that is supposed to be attached to this question is a picture of a flower showing both red and white spots as it colors, then the inheritance pattern shown is different from the other inheritance pattern because the normal inheritance pattern would only show one color. Normally, a flower would have a uniform color. In this case, only white or only red. The flower shows what we call, co-dominance. Red and white colors are both traits of the flower and the colors both manifest. In other traits, only the dominant trait is exhibited.

Answer:

Gametes from both dogs are needed to maintain the correct number of chromosome in the offspring

Explanation:

Reproduction in dogs is a sexual process. During the process, haploid gametes from both the male and the female (sperm from males and eggs from females) fuse together in a process known as fertilization in order to produce diploid offspring.

The haploid gametes ensure that the offspring produced during fertilization has the correct (diploid) number of offspring. Because the production of gametes involves meiosis and crossing over of genetic materials between chromosomes, offspring produced by sexual reproduction are usually genetically different from one another. The random fusion of gametes further ensures that offspring from the same parents are different from one another.

Answer:  

Determining bar temperature on Fahrenheit scale -

The temperature of the bar is given as 50 degrees Celsius.

If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.

We know

C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.

Now,

50/5 = (F-32) / 9

Or, (F-32) / 9 = 10

Or, F-32 = 90

Or, F = 90 + 32

Or, F = 112 degrees Fahrenheit.

That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

Explanation:

Answer: Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started. The residual volume (RV) is the amount of air that is left after expiratory reserve volume is exhaled. The lungs are never completely empty: There is always some air left in the lungs after a maximal exhalation.

So your answer will be Residual volume...

Hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D

It is left because exhaling will never remove all air from your lungs, if it did your body would shut down due to lack of oxygen to all organs. It distributed the atoms throughout the body.

The answers to your questions about genetic recombination are:

Independent assortment happens during metaphase I.

Fertilization happens during sexual reproduction.

Independent assortment is random chromosome alignment resulting in variation.

Answer:

Prokaryotes are highly distinguished from Eukaryotes, mainly on the basis of their nucleus type. As the word itself suggest that Pro means Primitive and Karyon means Nucleus, while Eu means Specialized and Karyon means Nucleus. Hence, Eukaryotes are more equipped than Prokaryotes. Prokaryotes are mainly found between  1-10 µ and Eukaryotes between 5-100 µ. Prokaryotes mainly have a poorly defined nuclear region with only nucleic acids called a Nucleoid and lack a nuclear membrane too. On the contrary, Eukaryotes have a well defined nucleus with a clear nuclear membrane. Also, The being primitive, prokaryotes have one strand of chromosomes while Eukaryotes have many (46). Prokaryotes also lack a lot of cell organalls. The ribosomes in prokaryotes and eukaryotes are 70's and 80's respectively. Also, photosynthetic prokaryotes have membranous vesicles for synthesis food, unlike Eukaryotic Plants that perform it with Chlorophyll.
