Which word equation best represents the process of photosynthesis?
A. Glucose-ATP+carbon dioxide
B. Glucose-carbon dioxide+water
C. Carbon dioxide+water-glucose+oxygen
D. ATP+glucose-water+carbon dioxide+oxygen

Answers

Answer:

B.s the correct answer

Explanation:

Surely it's not C or D because they have oxygen, and oxygen is a product of photosynthesis.

Surely not A because photosynthesis uses water too.

The answer is c

What evidence have you discovered to explain how Mendel’s experiments showed that traits in offspring are inherited?

Answers

Answer:PLZ MARK ME THE BRANISET

By examining large sample sizes, Mendel showed that his crosses behaved reproducibly according to the laws of probability, and that the traits were inherited as independent events. Two rules in probability can be used to find the expected proportions of offspring of different traits from different crosses.

To find the probability of two or more independent events occurring together, apply the product rule and multiply the probabilities of the individual events. The use of the word “and” suggests the appropriate application of the product rule. To find the probability of two or more events occurring in combination, apply the sum rule and add their individual probabilities together. The use of the word “or” suggests the appropriate application of the sum rule.

During a schoolyard survey, students observe a litter of baby rabbits with brown and white offspring. Explain how it is possible for two brown furred rabbits to have a white furred offspring. Use evidence to support your answer.
help asap

Answers

Answer:

Its a recessive gene

Explanation:

It was passed down by their grandparents, or great grandparents

The two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).

[tex]\frac{1}{4}[/tex] or 25% of the offspring will be white furred (bb) as shown in cross done with a Punnett Square (see attachment below for evidence).

Recall:

A recessive trait will be expressed in an offspring if two copies of the recessive genes for a trait are present in the offspring.

Let's assume the gene for brown fur is dominant over the gene for white fur.

Using B to represent gene for brown furb to present gene for white fur

Therefore, the two brown furred rabbits can produce white furred offspring if both parent stocks are heterogenous brown rabbits (Bb x Bb).

[tex]\frac{1}{4}[/tex] or 25% of the offspring will be white furred (bb) as shown in cross done with a Punnett Square (see attachment below for evidence).

Definitions:

• Evaporation –



• Condensation –



• Precipitation –



• Transpiration –



• Crystallization –



• Downhill flow –

Answers

Evaporation: Vaporization that occurs at the surface of a liquid below the liquid's boiling point.

Condensation: The change of state from a gas to a liquid.

Precipitation: Rain, snow, sleet, or hail that falls from clouds to the Earth's surface.

Transpiration: The water evaporates from the leaves of plants and moves into the air.

Crystallization: the formation of highly ordered, solid structures from particles in a solutions.

Downhill flow: If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow

Answer:

evaporation is the process of turning liquid into vapor

condensation is the conversion of vapor to liquid

precipitation is rain snow sleet or even hail that falls to the ground

transpiration is the exhalation of water vapor through the stomata

This gardener started with much smaller plants in this park. Over time, the garden has grown into a large display of brilliant flowers. What would you tell the gardener to explain how the plants have grown and flourished so successfully?

Answers

This is because

1.they are in the right habitat for those kinds of plants

2.the gardener is taking care of them like watering them and not watering when they are about to die or rarely watering them, and always giving them the right amount of water

3.the placement of the plants helps to, they are given the perfect amount of sun and nutrients from the ground

The photosynthetically active eukaryotes and living organisms that produce food are called plants.

The reasons which tell about how plants have grown are:

The planted plants are suitable for the area and are best to be grown in that habitat. They are acclimatized to the soil and can grow in that area due to conditions favourable to them.

The factors like watering the right amount and proper sunlight are the reasons that help the plant to grow.

The use of nutrients and the soil quality helps the plant to grow fast and flourish well.
