Answer:
Natural selection needs some starting material, and that starting material is heritable variation. For natural selection to act on a feature, there must already be variation (differences among individuals) for that feature. Also, the differences have to be heritable, determined by the organisms' genes.
Cells througout a multicellular organism develop different ways to perform various tasks - this is called cellular specialization and/or cell differentiation.

Explain how the electron transport chain makes ATP.
Answer:
t
Explanation:
While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.
Answer:
Explanation:
during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP
Difference between direct and indirect effect
Direct effects, as the name suggests, while not manipulated or communicated by a third party, deal with the direct influence of one entity on another. Indirect effects can be described as the influence, mediated or passed on by a third, of one organism or species on another.
An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure performs a similar function? A. cell membrane B. cytoplasm C. nucleus D. vacuole
Answer:
A. Cell membrane
Explanation:
The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.
The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.
Thus, the correct answer is option (A).
Answer:
A. cell membrane

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

Answer:
Have cones as reproductive structures.
Have vascular tissue.
Explanation:
The gymnosperms have vascular tissue and have cones as reproductive structures.
What are gymnosperms?The gymnosperms are woody like plants having a cone shaped structure, bear no flowers, no fruits but bear seeds; The seeds are with out coat and they are not covered by the fruit wall.
Gymnosperms produce seeds which are not enclosed in an ovary, while in Angiosperms the reproductive organs are the flower, they may involve in double fertilization resulting in a diploid zygote, and a triploid endosperm.
Gymnosperms produce seeds and fruits from their flowers, the flowers in gymnosperms helped in the propagation of the plants, it attract pollinators and attracted seed to dispersers, gymnosperms became dominant among plants.
The modification of the gymnosperm includes Modified leaves, Sunken stomata, Pointed and thick cuticle leaves, Less transpiration rate.

D. Gathering it can have a negative affect on natural habitats
The company's decision against using hydroelectric Energy as an alternative energy source might be Gathering it can have a negative affect on natural habitats.
Why is hydroelectric power not a good energy source?Hydropower can also cause environmental and social problems. Waterholes drastically change the landscape and rivers they are built on. Dams and reservoirs can decrease river flows, raise the water temperature, degrade water quality and cause sediment to build up. This has negative impacts on fish, birds and other wildlife.

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

Give an example of how Eubacteria can be beneficial. Explain. Please help me.
Answer:
Some bacteria are good for you, including the bacteria in your digestive system, or gut. These bacteria help to break down food and keep you healthy. Other good bacteria can produce oxygen are used to create antibiotics. Bacteria are used in food production to make yogurt and fermented foods.
An example of how Eubacteria can be beneficial is that these bacteria fix nitrogen for soil that can be used by living beings.
What are eubacteria?The bacteria in your gut and digestive tract are among the beneficial bacteria. These microorganisms aid in the digestion of food and promote good health. To make antibiotics, other beneficial microorganisms that can also produce oxygen are employed. Yogurt and other fermented foods are produced using bacteria in the food industry.
Oxygen, carbon, nitrogen, and phosphorus that living things like animals and plants cannot use can be converted by eubacteria into usable forms. In the soil, they fix the nitrogen that is present in the air.
Therefore, Eubacteria can help the environment by fixing nitrogen into the soil so that living things can use it.
