Describe the normal process of osteogenesis for compact and spongy bone using the three different types of bone cells and their functions

Answers

Answer:

Osteoblasts penetrate the disintegrating cartilage and replace it with spongy bone. This forms a primary ossification center. Ossification continues from this center toward the ends of the bones. After spongy bone is formed in the diaphysis, osteoclasts break down the newly formed bone to open up the medullary cavity.

ii) Explain briefly how these features contribute to the efficiency of photosynthesis?

Answers

Answer:

here's your answer

Explanation:

the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.

Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves

Regarding the "East Side Story" hypothesis, what would paleoanthropologists need to show that it was false?

Answers

Answer:

Evidence of fossil apes and hominids in both East and West of the great rift valley

Explanation:

The East Side Story hypothesis opined that a tectonic plate movement created a seismic split in the earth, thus deepened the rift valley and created a geographical barrier between the east and the west of the great rift valley. The barrier created a kind of geographical isolation between the ancestors of hominids, dividing them into two with each population taking different evolutionary paths.

Thereafter, the ancestors in the western side of the rift valley evolved into the chimpanzee's family while those in the eastern side ultimately evolved into humans.

Thus, providing the fossils of apes and that of hominids in both East and West sides of the great rift valley will render the hypothesis invalid.

A plant of genotype C/C ; d/d is crossed to c/c ; D/D and an F1 testcrossed to c/c ; d/d. If the genes are linked, and 20 map units apart, what will be the percentage of c/c ; d/d recombinants

Answers

Answer:

10%

Explanation:

The parental crossings = Cd/Cd   x  cD /cD

The distance the genes C and D = 20 map units

Determine the percentage of  cd / cd recombinants that will be formed

the distance shows that there is only 20% recombinant progeny

The recombinants are : CD/CD and cd/cd = 20%

i.e. each recombinant progeny = 20% / 2 = 10%

hence % of cd/cd recombinant = 10%

Vaccine are manufactured as an antigen against the disease-causing bacteria or virus and then administered to healthy individuals to produce adaptive immune response

The  type of medications are manufactured as an antigen against the disease- causing bacteria or virus and then administered to healthy individuals to produce adaptive immune response is Vaccines which is the third option.

Vaccines are medications that are manufactured as an antigen against disease-causing bacteria or viruses. They are designed to stimulate the immune system of healthy individuals to produce an adaptive immune response. By introducing a harmless or weakened form of the pathogen or its components into the body, vaccines mimic an infection and trigger an immune response. This allows the immune system to recognize and remember the pathogen, enabling a faster and more effective response if the person is exposed to the actual disease-causing agent in the future.

If 622 water molecules were removed during the synthesis of a specific polysaccharide, how many monomers were joined together to make this molecule? need help please and thank you ​

Answers

Answer:

623 monomers

Explanation:

In a dehydration synthesis reaction, one water molecule is removed for every bond that is created between 2 monomers.

Linking 3 monomers together would remove 2 water molecules.

Following this pattern, the number of water molecules removed will always be one less than the number of monomers that were joined together.

So, if 622 water molecules were removed, then 623 monomers were joined together.

The answer is 623 monomers.

21 Science 6 - CR Calculating the Density of Propane Use the mass and volume data to calculate the density of liquid propane to the nearest hundredth. Mass of propane = 4,300 g Volume of propane = 10,000 mL The density of liquid propane is g/mL. Intro​

Answers

Answer:

0.43g/mL

Explanation:

Density of a substance is its mass per unit volume. It can be calculated thus:

Density = mass/volume

According to the information provided on propane in this question;

Mass of propane = 4,300g

Volume of propane = 10,000mL

Density = 4300/10000

Density = 0.43g/mL

Hence, the density of propane is 0.43g/mL.

Which of the following statements regarding membrane protein function is false? Group of answer choices Membrane proteins act as receptors to molecules like hormones. Membrane proteins serve as enzymes. Membrane proteins form junctions between cells. Membrane proteins transfer genetic information to the cytoplasm.

Answers

Answer:  

Membrane proteins transfer genetic information to the cytoplasm.

Explanation:

Membrane proteins cannot transfer genetic information to the cytoplasm. Genetic information is only in DNA and RNA, and to pass it, RNA has to leave the nucleus and be translated into a protein in the cytoplasm. Once the protein synthesis has finished, the protein may go to the membrane if it has the signal to do it or have a different function. In the membrane, the membrane protein can receive information from other cells and transfer it to the cytoplasm, but never in the shape of genetic information.

c. lateral buds: 2. Brussels sprouts

d. modified stem: 6. Potato

e. leaf (petiole and blade): 4. Spinach    

f. petiole: 3. Celery

Explanation:

A plant stem is one of the structural axes of vascular plants that holds structures such as leaves, flowers, and fruits. The stem also transports water and dissolved (organic and inorganic) nutrients between the roots and the shoots. In some plants, the stem is modified in order to carry out other functions (e.g., storage, vegetative propagation, protection, etc). Potatoes are modified stems (i.e., stem tubers) ​that are connected by small stem sections known as stolons, and serve as food storage organs. A taproot is a central, and dominant root from which other roots sprout, which can be used by the plant to store water and food (e.g., in carrots and turnips). Lateral buds or axillary buds are meristematic regions growing from the axils of the leaves at the intersection of the leaf and stem, below the terminal bud. Leaves are composed of the 1-blade, also known as the lamina, which is the largest part of the leaf, and 2-the petiole, which is a stalk that supports the blade and connects it to the plant stem. Celery petioles play the same functions as a plant stem by acting as transport and storage organs.

a. Contains an F' his+ trp
b. Has become F-
c. Contains an Hfr translocation
d. No longer mates as a merry diploid
e. Not enough information is given

Answers

Answer:

The correct answer is - b. has become F-.

Explanation:

In the case of the cross of two different strains, some genetic material moves to the F- strain from the Hfr strain, but due to genome size, it's not possible that all the genes can pass into a single bacterium.

Instead of complete transfer, each individual F- cell gets a different and random subset of genes from the Hfr. There is no translocation and F' does not contain  his+ trp+.

7. Shawn plotted the data in a bar graph with two bars: one representing the number of bees per colony in the control cages and the other representing the number of bees per colony in the cages exposed to the fungicide. If the results support the hypothesis that fungicides harm bee development, what would you expect this bar graph to show? Describe the expected pattern in a few sentences.

Answers

Answer:

The first bar increases in length as compared to the second bar.

Explanation:

The length of the bar of control cages in graph increases because the number of bees per colony increases while on the other hand, the length of the bar of the cage that is exposed to fungicides decreases because the bees are negatively affected from the application of fungicides. They act abnormal in behaviour and adversely affected the reproduction of bees that greatly affected its population.

Elephants are considered K-strategists because they give birth to only one calf at a time and most have five years in between having another calf. Calves stay under the protection of the mother and her herd until maturity at 10-15 years of age. What type of survivorship curve do elephants tend to follow

Answers

Answer:

Type I curve

Explanation:

The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).

In a diploid cell, a FISH probe should produce ____________ signals in metaphase FISH and ____________ signals in interphase FISH.

Answers

Answer: Four, two

Explanation:

FISH (fluorescence in situ hybridization) is a technique for chromosome mapping with probes that emit fluorescence and allow the visualization, distinction and study of chromosomes of nuclei in metaphase or inferophase. In this way, any type of anomaly such as inversions, aneuploidies, duplications or microdeletions can be seen. To do this, a non-specific DNA staining is performed with DAPI (a fluorophore that marks the nucleus where DNA is present) and the fluorescence will be seen under the microscope.

When cells are in metaphase, their chromosomes are condensed in preparation for cell division. To stop them in metaphase, colchicine is used which is a microtubule depolymerizing agent responsible for separating the sister chromatids of a chromosome, thus preventing the progression of cell division and arresting the cell cycle in metaphase. Here we will see translocations, microdeletions or duplications.

Interphase FISH is used to see decondensed chromatin, which allows higher resolution in detecting small abnormalities. It is mainly used for the detection of aneuploidies or large deletions, duplications or translocations when samples are difficult to grow or are scarce, as in the case of fetal or tumor cells. It is not possible to distinguish between a normal karyotype and a karyotype showing a balanced translocation. In addition, it can be used in the analysis of solid tumors, which divide very infrequently.

During metaphase, the chromosomes are duplicated so there would be two sets of chromosomes (a total of four chromosomes). Then, there would be four signals for each probe. During interphase, the chromosomes are not dupicated. Since it is a diploid organisms, there would be two chromosomes and this will represen two signals for probe.

Recall that one approach to the study of cell cycle regulation has been to fuse cultured cells that are at different stages of the cell cycle and observe the effect of the fusion on the nuclei of the fused cells (heterokaryons). When cells in Gl are fused with cells in S, the nuclei from the Gl cells begin DNA replication earlier than they would have if they had not been fused. In fusions of cells in G2 and S, however, nuclei continue their previous activities, apparently uninfluenced by the fusion. Fusions between mitotic cells and interphase cells always lead to chromatin condensation in the nonmitotic nuclei. Based on these results, identify each of the following statements about cell cycle regulation as probably true (T), probably false (F), or not possible to conclude from the data (NP). Sort each statement into the appropriate bin.
1. The transition from mitosis to G1 appears to result from the disappearance or inactivation of a cytoplasmic factor present during M-phase.
2. The activation of DNA synthesis may result from the stimulatory of one or more cytoplasmic factors.
3. Gl is not an obligatory phase of all cell cycles
4. The transition from G2 to mitosis may result from the presence in the G2 cytoplasm of one or more factors that induce chromatin formation.
5. The transition from S to G2 may result from the presence of a cytoplasmic factor that inhibits DNA synthesis.

Answer:

1. T

2. T

3. NP

4. F

5. F

Explanation:

In somatic cells, the cell cycle can be divided into 1-the interphase, 2-the mitotic phase or M phase, and 3-the G₀ phase. In turn, the interphase of the cell cycle can be divided into three phases: 1-the gap 1 (G1) phase or growth 1 phase, 2-the S phase (DNA replication or DNA synthesis), and 3-the gap 2 (G2) phase or growth 2 phase. During the G1 phase, the cell synthesizes key enzymes which are required during DNA replication (S phase) and cell division (M phase). Cytoplasmic factors are proteins and messenger RNAs (mRNAs) that control cell functions during the cell cycle. This cycle is modulated by proteins known as control factors, i.e., cyclins and cyclin-dependent kinases (Cdks) that work together to control the progression through different phases of the cell cycle. The transition from S to G2 occurs after DNA replication. This transition (S to G2) is controlled by a DNA damage checkpoint orchestrated by the ATM (Ataxia telangiectasia mutated) and ATR (Ataxia Telangiectasia and Rad3 related) kinases which are recruited to DNA damage sites. Moreover, the ​transition from G2 to M phase is mediated by the accumulation of mitotic inducers, which lead to an increase in the activity of mitotic kinase and finally trigger mitotic entry.
