please help me. i will love u forever

Answer:

Yes.

Explanation:

Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon  is called ecological succession.

Answer: CORRECT (SELECTED)

Secondary succession

Explanation:

Secondary succession occurs when a previously occupied area is recolonized after a disturbance kills most, or all, of its community.

Sound waves propagate from the sound source. The sound through radio comes through the electrical signal, radio wave, and sound wave. Thus, option D is correct.

A sound wave is an acoustic wave that travels through a medium through the disturbance of the particles in a longitudinal direction. A few examples are radio, whisper, rustling, etc.  

The sound waves in radio first get converted into the electrical signal that passes through the circuit of the radio that further gets transferred as radio waves.

These radio waves are the part of the electromagnetic spectrum that travels at a little less speed than light. The radio waves again get converted into sound waves as it leaves the system and reaches the ear of the organism.

Therefore, option D. sound wave → electrical signal → radio wave → sound wave is the correct order.

A. Genetic drift

Answer:

animal release carbon dioxide into the atmosphere through respiration

Explanation:

When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.

Animals breathe, taking in oxygen and releasing carbon dioxide. Animals release carbon dioxide gas into the outer atmosphere through respiration process.

This process completes in two steps: external respiration and internal respiration. External respiration, or breathing, includes inhaling (inhalation) oxygen from the outside atmosphere and exhaling (exhalation) carbon dioxide to outside. In this process, gas exchanges take place at the lungs, and deoxygenated blood oxygenates before going back to the left heart.

In cellular respiration, the cell takes oxygen from the oxygenated blood and uses it in different cellular metabolic reactions, releasing carbon dioxide into the blood. So in cellular respiration, oxygen is taken up by the cell and carbon dioxide is released by the cell. This carbon dioxide goes to the lungs, and by the process of exhalation, it is released into the atmosphere.

Hence, animals release carbon dioxide into the atmosphere through the respiration process.

7 m/s

Explanation:

Acceleration,

Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.

Making v the subject then

v=at+u

Taking u as zero then

Substituting 3.5 for t, 2 as a then

v=3.5*2=7 m/s

Explanation:

Crossing over accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical

Answer:

Cell respiration occurs in all eukaryotes

Answer:

44 N

Explanation:

Force applied can be calculated using the formula as follows;

F = m.a

Where;

F = force (Newton)

m = mass (kg)

a = acceleration (m/s²)

According to the information provided in this question, mass of shot put = 5.5kg, acceleration = 8m/s². Hence;

F = m × a

F = 5.5 × 8

F = 44 Newtons

The force needed by the shot putter is 44N.

Answer: The question is incomplete because the options were not given but the options has been gotten from another website.

Here are the options.

a. Wood is routinely recycled to make new wood-based products.

b. Wood products can be manufactured from different tree species.

Eliminate

c. Wood may be replenished by planting new trees to replace those being used.

d. Wood products can be manufactured using various other materials such as plastics.

The correct option is c.

Wood may be replenished by planting new trees to replace those being used.

Explanation:

This is because wood is a Renewable resource because Renewable resources are resources that can be replenish or reproduce again after usage either by naturally producing another one. Theses resources are not exhausted because they can naturally be reproduce again. Wood is a Renewable resources because new ones are planted to replaced the used ones.

Answer:

The correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

Explanation:

In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.

In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

Answer:

Budding

Explanation:

The common asexual method of reproduction by hydras is budding. Buds originate at the junction of the stalk and gastric regions. The bud begins as a hemispherical outpouching that eventually elongates, becomes cylindrical, and develops tentacles. The bud then pinches off and a new individual becomes independent. Buds are produced every two to three days under favorable conditions. Following unfavorable conditions, such as injuries or periods of scarce resources, hydras occasionally reproduce through transverse and longitudinal fission.

Answer:

25%.................

Answer:

D, 25%

Explanation:

We can do this with simple math! Since we have a 1:4 ratio of possibly expressing the recessive phenotype, we will do 1/4.

1/4 = .25

Then, we will multiply this by 100, which results in 25.

Answer:

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane.

Explanation:

Answer:

Yes.

Explanation:

Yes, amino acid can not be factor or broken down because it is the smallest unit of proteins. Proteins are made up of about 20 small amino acids. Proteins can be factor into amino acids but amino acids can't be factor into proteins because proteins are made up of amino acids but the amino acids does not formed from proteins so that's why Tim does not factor his amino acid  into total protein.

Answer:

The correct answer is - 0 m/s.

Explanation:

In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.

'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.

Answer Blood vessels deliver oxygen and nutrients to virtually all cells in developing mammalian embryos and adults, whereas lymphatic vessels drain the interstitial fluid that collects in tissues, and serve as a conduit for immune cell trafficking and fat absorption.

: Lymphatic capillaries collect lymph fluid from the tissues, which allows them to regulate the pressure of interstitial fluid. This fluid is essentially plasma that leaks out of cardiovascular capillaries into the tissues due to the forces of hydrostatic or oncotic pressure.
