Answer:
by weathering and becoming new parent material
Explanation:
Soil formation occurs as a result of the the decay or the remains of plants and animals which are used up.
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Hence, the type of bedrock under a soil affect the characteristics of the soil by weathering and becoming new parent material i.e the contribution of small rock particle to the soil.
the structure labeled A in the figure below is called the
Answer:
Centromere
Explanation:
Connects sister chromatids
The structure labelled A in the figure is a centromere.
What is a centromere?The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.
The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.
Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted
The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

1s orbital
Explanation:
The electron has to go into the first energy level, in the 1s orbital. Helium, with two protons, will have two electrons. These are placed one at a time into the 1s orbital. This makes helium a very contented atom.
what was the speed of a car that traveled 240 m in 12 s
Answer:20
Explanation: Because when you divied 240 by 12 you get 20.
240/12=20
Answer:
20m/s
Explanation:
Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?
Explanation:
Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.
Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.
The overall equation for this pathway is:
1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

Answer:
The sulfur cycle describes the movement of sulfur through the geosphere and biosphere. Sulfur is released from rocks through weathering, and then assimilated by microbes and plants. It is then passed up the food chain and assimilated by plants and animals, and released when they decompose.
What 3 types of science formed the geological time scale?
a) archaeology, paleontology, astrology
b) Scientology, astronomy, and geology
c) geology, archaeology, and paleontology
d) paleontology, Scientology, and biology
Answer: c) geology, archaeology, and paleontology
Explanation:
The geological time scale can be defined as a scale which is used to determine the chronological dating of the organisms in the geological strata. It helps in determining the occurrence and existence of particular kind of species on planet earth. It can also be used to trace the development and passage of a particular kind of trait from one generation to the another. It can also be used to trace back various geological events that occurred on planet earth like volcanic eruption, plate tectonics, and others. The geologists used it for tracing the geological activities that occurred in the history of earth. Archaeologist study about rocks and fossils to trace back the geological time scale. Paleontologist study the existence of a particular species via studying the fossil evidences and reconstructing the primitive conditions by developing a geological time scale. They trace the evolutionary history of organisms.

describe the feature of cell mbrane
Answer:
The cell membrane or plasma membrane is a biological and thin semi-permeable membrane that surrounds the cytoplasm of a cell
Explanation:
1. Explain how the atomic number and mass number of an atom can be used to determine the number of
electrons and of neutrons respectively.
Because the total of neutron and proton/electron is the atomic mass. So if you wanna find proton/electron and you know the neutron, just minus the atomic number with the neutrom and you will get the proton
Here if you need the formula
Atomic number = Total neutron + Total proton or electron
prostate cells usually require testosterone and other androgens to survive. but some prostate cancer cells thrive despite treatments that eliminate androgens. one hypothesis is that estrogen, often considered a female, may be activating genes normally controlled by an androgen in these cancer cells. desribe one or more experiments to test this hypothesis
One can check for the translation and transcription of genes of interest in the absence of androgens, one can check whether the estrogen is involved in the expression of oncogenic proteins of interest by depleting the estrogen, and one can also examine the existence of estrogen receptor complex in the prostrate cancer cells nuclei.
• One can check for the translation and transcription of genes of interest in the non-existence of androgens and if these genes are expressed then this suggests that apart from androgens other factors also affect their expression.
• One can deplete the estrogen from cancer cells and if the involvement of estrogen is there in the expression of oncogenic proteins of interest then its reduction will result in diminished multiplication rates in cancer cells.
• One can also test the existence of estrogen-receptor complex in the prostate cancer cells nuclei to confirm that estrogen is taking part in the regulation of gene expression.
Thus, various experiments can be conducted to check that whether the expression of genes controlled by the androgens under normal conditions are affected by the presence of estrogens in prostate cancer cells.

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular chromosome are found in four different species: First sequence: STUVWX Second sequence: UVXTSW Third sequence: UVWSTX Fourth sequence: SWVUTX Assuming that the arrangement in the first sequence is the ancestor/reference arrangement, in what evolutionary order did the four species arise, such that the fewest number of inversions occur between each species (place the first sequence as the earliest species in your ordering)2341
Answer:
The correct answer is - 1, 4, 3, 2.
Explanation:
It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX
After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:
STUVWX
SWVUTX
Thus the second sequence after Ist inversion would be SWVUTX
2nd inversion, Third sequence:
SWVUTX
UVWSTX
Thus the third sequence after 2nd inversion is UVWSTX
3rd inversion, fourth sequence:
UVWSTX
UVXTSW
Thus, the fourth sequence after 3rd inversion is UVXTSW
brief explain the roles of the following in photosynthesis 1 NADP 2) Ribubose diphostate 3) photosytem 1 ad 2
Answer:
1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.
3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II
● PhotosystemSII acts first during the light transformation process in photosynthesis.
● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from
plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.
