Rough-skinned newts produce a strong toxin called TTX as a defense mechanism against predators. Garter snakes can
tolerate a very limited amount of the toxin. However, several populations of garter snakes have recently shown an
increased tolerance for TTX. The different populations of snakes have independently acquired a gene variation that
allows them to better block the effects of the toxin.

Answer:

The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]

Explanation: Plant cells respire the same way animal cells do, but respiration is only one part of the process. To survive, plants also need another chemical reaction called photosynthesis. While both plants and animals carry out cellular respiration, only plants conduct photosynthesis to make their own food.

Answer:

Cell size is limited by a cell's surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell's function is determined, in part, by its shape.

Answer:

A) fish, snail, and plants

Explanation:

Transpiration is the evaporation of water at the surfaces of the spongy mesophyll cells in leaves, followed by loss of water vapour through the stomata . Transpiration produces a tension or 'pull' on the water in the xylem vessels by the leaves. Water molecules are cohesive so water is pulled up through the plant.

Transpiration is the outcome of the association between the xylem vessels and stomata present in the leaves.  

• The evaporation of water at the surfaces of the spongy mesophyll cells in the leaves succeeded by the loss of water vapor via the stomata is termed transpiration.  

• Transpiration generates a pull or tension on the water in the xylem vessels, and these molecules of water are cohesive so pulling up of water takes place through the plant.  

• The primary sites of transpiration are the stomates present in the leaves. This stomata comprises two guard cells, which produce a small pore on the leaves' surfaces. These guard cells monitor the closing and opening of the stomates in reaction towards different environmental stimuli, and thus, regulate the loss of water by transpiration.

Answer:

I think that the answer is False.

Explanation:

Answer:

The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores. Tertiary consumers eat the secondary consumers.

Explanation

An animal that eats producers is called herbivore. Therefore, option (D) is correct.

Herbivores eat plant matter such leaves, stems, fruits, and seeds. These organisms get energy and nutrients from producers, the main source of organic matter in ecosystems.

Cows, rabbits, deer, and many insects are herbivores. Herbivores transform plant biomass energy into a form that higher trophic levels can consume, making them vital to ecosystem energy and nutrient cycles. Therefore, option (D) herbivore is the correct option.

Answer:

your answer would be B.  the vascular tissue

Explanation:

There are two principal tissue types that make up the veins of plants: The xylem moves water and minerals. This flows from the plant’s roots upwards. The phloem moves food energy around the plant. This flows in whichever direction the plant needs it to flow. These two tissue types make up the vascular bundle of the plant.

Answer:

Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.

Explanation:

In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase

The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.

Explanation:

Hi here is your awnser: Natural selection is the process by which organisms with variations most suited to their local environment survive and leave more offspring. In natural selection, the environment—not a farmer or animal breeder—influences fitness. Well-adapted individuals survive and reproduce.

Answer:

The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.

Explanation:

As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.

Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.

Life Cycle of a Star

Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.
