What is the element or compound in the Phosphorus Cycle and why is it important to living things?
Answer:
Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils). Insufficient phosphorus in the soil can result in a decreased crop yield.
Explanation:
Answer:
Thus, phosphorous is crucial to living organisms because ATP is crucial. Phosphorus is also important because it makes up our DNA. Phosphate is part of the so-called ladder legs which Adenine, Thymine, Guanine, and Cytosine bind to see. It holds this same job in RNA.
Explanation:
In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?
Answer:
Rr and rr
Explanation:
The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).
Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).
Rr x rr
Rr Rr rr rr
Rr = red
rr = white
If the red parents is true-breeding
RR x rr
Rr Rr Rr Rr
All their offspring would be red without any white flower color.
Hence, the genotypes of the parent are Rr and rr.

During a reproductive process, paired chromosomes often swap lengths of DNA at random. This process further increases the number of new genotypes created in each generation This helps explain why, in
species that reproduce sexually, no two siblings (except identical twins) look exactly alike. With all that recombination, you can end up with your mother's eyes, your father's nose, and how that combines
qualities from both parents. SC 012 L 16.14
Which mechanism produces this genetic diversity?
Y chromosome syndrome
Asexual reproduction
Crossing over
Mitosis
Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.
What is Crossing over?When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the formation of egg and sperm cells (meiosis).
This mechanism leads to novel allele combinations in the gametes (egg or sperm) generated, ensuring genetic variety in any baby born.
Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up. When two chromosomes — one from the mother and one from the father — line up, parts of the chromosome can be switched.
Therefore, Crossing over is when the alleles cross over and pair up, resulting in the genotype for an offspring.

The deltoid muscle can effectively contract through its entire ROM because of the upward rotation of the scapula, which serves to maintain tension in the deltoid muscle. If the deltoid loses tension, it becomes
Answer:
Actively insufficient
Explanation:
The deltoid is a muscle attached by tendons to the bones localized on the top of the shoulder (clavicle, scapula and humerus). The amount of force generated by a multi-joint muscle decreases as the muscle moves the joints simultaneously. A multi-joint muscle becomes actively insufficient when it shortens over both joints simultaneously and it no longer has the ability to develop an effective tension. Moreover, a muscle is passively insufficient when it can't be stretched to its fullest length across multiple joints simultaneously.

What is ATP?ATP, sometimes referred to as adenosine triphosphate, is a chemical that transports energy inside of cells. It is produced as a byproduct of photophosphorylation, which adds a phosphate group to a molecule using light energy, cellular respiration, and fermentation. It serves as the primary energy currency of the cell.
All forms of life utilize ATP. In addition to being used as an energy source, it is also integrated into deoxyribonucleic acid (DNA) during DNA synthesis and utilized in signal transduction pathways for cell communication.
Therefore, Energy is released from ATP when a fourth phosphate is added to the molecule the last phosphate bond is broken.

Answer:
Atom, molecule, cell, tissue, organ, organ system, and organism.
Explanation:
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the body's major organizational levels.
What are the levels of organization in animals?Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization that may be found in the body. These levels range in complexity from the simplest to the most sophisticated.
Cellular level is key. A cell is the smallest self-replicating unit of life. All cells share a few cells, despite differences in design and capacity. Cells contain nucleic acids (DNA and RNA), cytoplasm, and a lipid-based film. Cells have organelles in their cytoplasm that perform distinct functions.
Tissues are clusters of related cells that function together. Connective tissues provide organs shape and structure. Muscle cells contract to allow movement. Epithelial tissues cover organs, skin, and the stomach. Specialized cells in nervous tissue, the spinal cord, and the brain transform information using electrochemical impulses.
Organs are structures made of tissues that perform biological activities. Organs have tissues. Organs combine tissues to perform a certain purpose. Size and complexity of organs vary tremendously. Organs include the heart, lungs, and brain. The next level, organism level, is formed of different organs to maintain the body.

The Wunderlich Farms Boer Goat has a 4 chambered stomach and chews it's cud to assist with digestion. What type of adaptions are these?
A. 4 chamber stomach = behavioral and chewing cud = internal structural
B. 4 chamber stomach = external structural and chewing cud = behavioral
C. 4 chamber stomach = internal structural and chewing cud = external structural
D. 4 chamber stomach = internal structural and chewing cud = behavioral
Answer:
The answer is option A "4 chamber stomach = behavioral and chewing cud = internal structural"
Explanation:
Goats and other ruminants do not digest food directly as they eat their food and the reason is that ruminants do not have the enzymes that are necessary for breaking down the food directly as they eat so digestion in ruminants and particularly Goats has to undergo processes or procedures before the final digestion takes place.
All the processes in digestion for ruminant animals takes place in their four chambered stomachs which are the Rumen, Reticulum, Omasum and Abomassum.
In the four chambered stomach of Goat, the type of adaptation is behavioral and chewing cud which is the internal structure.

Answer:
Morula.
Explanation:
A zygote is the product resulting from fertilization. During the journey of the zygote through the fallopian tubes, until its implantation in the uterus, it divides many times, thus going through different phases. From the 16 cells it is called a morula, this stage represents the set of cells from the division of the fertilized ovum, in the first stages of embryonic development. It represents an intermediate phase between the zygote and the blastocyst. The morula stage is characterized by the fact that the replicating cells are all the same size, and there is no differentiation of organs.
