Jacob’s family traveled frequently by road. On a trip, he noticed that a large forest area appeared to have burned a few weeks a

go. Along the burned area, new pine trees were sprouting. Their cones release seeds when heated. How will this affect the future vegetation of the forest
a , The new seeds cannot grow like older trees due to fire damage.


b , The ashes from the old trees will be poisonous for the new plants.


c , The trees will grow and the forest will be restored to its original form.


d , The trees cannot live long since all the nutrients in the soil were burned

Answer:

c  The trees will grow and the forest will be restored to its original form.

Explanation:

The ashes from the old trees will serve as nutrient for the new plants. its restores back the ecosystem because the old tress and ashes will decay which will return nutrient to the soil.

the new seedlings will be exposed to fresh air and sunlight which improve there germination.

Which of the following are electron carriers in many important cellular processes?
GalinKa [24]

Answer:

1. B. NADH

2. B. hydrolysis of ATP.

3. C. ATP is produced from protein.

4. Option C.

5. Option C. Oxygen

6. Option D. Glucose.

7. Carbondioxide.

8. Metabolism.

9. Electron carriers.

10. Electrons.

Explanation:

Cellular respiration is a series of metabolic processes that break down sugars or food to produce energy. ATP is the cellular energy produced during cellular respiration. Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation. During cellular respiration, glucose is broken down into carbondioxide and water. Along the way, ATP is produced from the processes that transform glucose.

How can histograms help you describe a population? Use the word bank above to help you explain your answer.
krek1111 [17]

Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

Explanation:

A histogram is a graphical representation of a variable using bars. In such a bar, <u>its area is proportional to the frequency of the values represented</u>. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest.  On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented.  Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).

<u>Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.</u>

The glucose-making part of photosynthesis takes place in the.
romanna [79]

Answer:

The glucose making part of photosynthesis takes place in the stroma

explanation:

Stroma is the colorless liquid that surrounds the grana in the chloroplast inside plant cells. The stroma contains grana, and stacks of thylakoids in which photosynthesis is started before the chemical changes are completed in the stroma itself. The stroma functions by synthesizing organic molecules from water and carbon dioxide. In the stroma, an enzyme removes the carbon from carbon dioxide, and then combines it with hydrogen and oxygen and to form a simple carbohydrate molecule (glucose).

d-produces secretory proteins

e-modifies and sorts proteins

f-digests proteins

g-generates ATP

Explanation;

Some organelles and structures that make up the cell include; mitochondria, ribososmes, cell membrane, endoplasmic reticulum, golgi apparatus, lysosomes, among others,

-These organelles play individual roles in the cell; For instance;

Mitochondria-generates ATP

Lysosomes; digests proteins and worn out organelles

Golgi apparatus; modifies and sorts proteins

Ribosomes; Produces proteins

Endoplasmic reticulum; sythesis of lipids

Cytoskeleton; it gives the cell its shape

Nucleolus; manufactures and assembles ribosomes

etc.
