One day, at a certain time, a student measured the shadow of a fence and found that it was 2 m long. The next day, she measured the shadow of the same fence at a different time and found that it was 3 m. long. What can you infer about the time of day at which the student measured the shadows? Explain.
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.
Water cycle -
When water is removed from the soil and subsurface
water flows via roots to be used by the plant. Most of
the water that plants uptake passes though into the
atmosphere.

This is the process of transpiration because it has to do with plants!
(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
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.

The process by which the organisms that are better adapted to the environment survive and reproduce is called
.
Answer:
Natural selection
Explanation:
Answer:
The awnser is Natrual Selection :)
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.
What are the two main phases of photosynthesis called and why?
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.

Do plants and animals both use cellular respiration? Explain.
Answer:
yea
Explanation:
just took a test today
Answer: yes
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.

During transpiration, water moves through a plant and moves out into the atmosphere through the leaves. Transpiration is the result of the interaction of which two parts of a plant?
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.

carnivores
consumers
Od
herbivores
I’m
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.

What factors limit the size of a cell?
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:
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.

What will occur if a species is divided into two groups and allowed to reproduce in different environments for many generations?
Answer:
The original species will diverge into two new species. It will occur speciation. It will occur some sort of allopatric speciation.
Explanation:
When the original species is divided and placed under different environments, where they can reproduce for many generations, many changes or mutations will occur in each group. These changes will depend on each group´s environment and its ecological pressures and will lead to divergence. Pressures act on individuals and make them adapt to the new environmental conditions. Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce. The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.
The biological concept of species states that individuals of the same species can reproduce because they have a genetic reservoir in common: many genetic variants.
Genetic variability is the measure of a species organism´s tendency to differentiate. In genetic variability, individuals of the same species are not identical. They are recognizable as members of the same species, but they differ in shape, function, and behavior. There exist variations among individuals of the same species.
Genetic variability originates from mutations, recombinations, and karyotype alterations. It allows or makes possible evolution.
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flux, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
The process of allopatric speciation involves different steps:
• The emergence of the barrier.
• Interruption in the genetic interchange
• The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
• Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
• Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Answer:
divergence, potentially giving rise to two different species
