Which two phrases most likely explain how the rock shown here formed?
D A. Cooling of volcanic lava on Earth's surface
O B. Sedimentation of layers at the bottom of a body of water
O C. Small grains of sand getting pressed together over time

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited.[1] In other words, it is the gradual growth of an ecosystem over a longer period of time.[2][3]

Primary succession occurring over time. The soil depths increase with respect to the increase in decomposition of organic matter. and there is a gradual increase of species diversity in the ecosystem. The labels I-VII represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.

In contrast, secondary succession occurs on substrate that previously supported vegetation before an ecological disturbance from smaller things like floods, hurricanes, tornadoes, and fires which destroyed the plant life.[4]

Answer:

Most often there is a unicellular alga chlamydomonas. It moves in water with the help of two flagella located on the front, narrower end of the cell. Outside the chlamydomonas is covered with a transparent membrane, under which there is a cytoplasm with a nucleus, a red "eye" (a photosensitive body of red color), a large vacuole filled with cell juice, and two small pulsating vacuoles. Chlorophyll, contained in the chromatophores, gives a green the cell a green color.

I would appreciate brainliest, if not that's okay!

Answer:

analysis/presentation

Explanation:

please mark me as brainliest answer

The third step in fieldwork for marine science is analysis/presentation, Thus option "B" is correct.

Marine science recreates key role in the ongoing search to understand our world and to control its resources.

The interdisciplinary nature of the Marine Science curriculum will organise students to analyze deeply such co occuring issues as environmental alter, human clashes on the ocean, and biodiversity.

Thus option "B" is correct.

Answer:

Explanation:

feet

Answer:

Ss (male) × Ss (female)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. Based on the information in this question, the allele for short hair (S) is dominant over the allele for long hair (s). This means that a guinea pig will only be phenotypically long-haired if the genotype is "ss".

According to this question, Two short-haired guinea pigs are mated several times. Out of the 100 offsprings produced by this cross, 25 of them have long hair (recessive). This means that the phenotypic ratio of this cross is 3 short hair : 1 long hair i.e. 100 - 25 = 75 short hair. 75/25 = 3/1 = 3:1

To produce this phenotypic ratio, the parents must both be heterozygous (Ss) for the hair length gene.

Answer:

d

Explanation:

Answer:

1. that DNA is passed between cells during cell division

2. that the cells of all organisms within a similar species are mostly the same, both structurally and chemically

3. that energy flow occurs within

Explanation:

These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within

The group of choices associated with the question is as follows:

A)The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.

B)The hominids with the most closely matching leg bone measurements are likely more closely related than the others, due to the importance of locomotion as an evolutionary adaptation.

C)The femur measurements are not important.

D)Because the measurements of the leg bones vary widely, it is probable that the four species are from different genera.

Answer:

The correct answer is - The four primates likely share a close common ancestor or could potentially be the same species based upon the jaw measurements.

Explanation:

On the basis of the research, it is found that the four primates have similar jaw structure and measurement and have a distinct length of bones of the leg.

The given research and founding suggests that all four primates most likely share a close common ancestor or diverge from the same species based on her jaw measurements.

Answer:

Resting membrane potential; voltmeter; neuron; interstitial fluid; -70; outside; inside.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

The relative difference in charge across a plasma membrane is the resting membrane potential in an inactive excitable cell. A voltmeter is used to measure the voltage difference across the plasma membrane. This is done by placing one microelectrode into the neuron and the other microelectrode outside the neuron into the interstitial fluid. The RMP has a value that is typically -70 millivolts. More positive ions reside outside a neuron than inside a neuron when it is at rest.
