megakaryocytes are huge cells found in red bone marrow that extend long tendrils into blood sinusoids. The flow of blood breaks off small portions of those tendrils creating the formed element known as
Answer:
Platelet
Explanation:
In 1906 James Homer Wright established that platelets, seen as hyaline bodies or vacuoles, are formed in the cytoplasm of megakaryocytes in the bone marrow, which then disintegrate and pass as platelets into the circulation. Megakaryocytes are cells of the myeloid lineage. They originate platelets (or thrombocytes) by cleaving parts of their enormous cytoplasm directly into a sinusoid vessel. The function of platelets is to form thrombi to prevent blood loss in small blood vessel ruptures.
In ecosystems, biotic an abiotic factors influence one another. Give three examples of an interaction between a biotic and abiotic factor in any of the marine ecosystems from the chart. (Use the back for more room).
Answer:
One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.

What would be the correct complimentary DNA strand given the following DNA strand.
DNA: ATACGAAAT (Type as one word - no spaces)
Using the same strand of DNA, what would be the correct sequence for an RNA strand? (Type as one word - no spaces)
Answer:
TATGCTTTA for question 1.
For RNA following the original strand it would be UAUGCUUUA
Explanation:
Replace A with T(vice versa), and C with G(vice versa)
But for the RNA, A bonds with U instead of T. So it would be the same as the complimentary DNA, just with U instead of T
In the laboratory, yeast cells are usually grown at a temperature of 25oC. A scientist wanted to determine if yeast cells would reproduce faster or slower when the temperature was dropped to 15oC. The same number of yeast cells were placed in the same medium with the same amount of nutrients. One sample was kept at 25oC and the other one was kept at 15oC. The number of yeast cells was counted every hour for an eighteen hour period.
Answer:
This question is incomplete, however, it is asking to identify the following variables:
Independent variable: Temperature
Dependent variable: Number of yeast cells
Constants: same amount of nutrients, same number of yeast cells, same medium
Explanation:
- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.
- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.
- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.
What are the kingdoms of life that scientists use to classify organisms?
A. Bacteria, Protista, Fungi, Plantae, Animalia, Phylum
B. Archaebacteria, Phylum, Family, Plantae, Animalia, Eubacteria
C. Eubacteria, Archaebacteria, Protista, Fungi, Phylum, Species
D. Eubacteria, Archaebacteria, Protista, Fungi, Plantae, Animalia
Answer:A
Explanation:
Organisms are classify on the basis of kingdoms Bacteria, Protista, Fungi, Plantae, Animalia, Phylum. Therefore, option (A) is correct.
How do we classify organisms?Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.
It is divided into phyla or divisions, which are further subdivided into classes. Further divisions include order, family, genus and species, in that order. Thus, species is the basic unit of classification.
Organisms are usually grouped together based on their unique characteristics. The classification of an organism often provides useful information about its evolutionary history and which other organisms are related to it.

In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?
Answer:
50%
Explanation:
Draw a Punnet square to determine the percentage of offspring that are tall.
The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)
Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.
From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.
Required percentage

how do plants grow helppp
Answer:
During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.
Answer:
Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.
Explanation:
The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds. The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.

In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).
