Medulla is a set of cells that run through a piece of hair. forensic scientists use them to determine which creature the hair came from.

Answer: Jamila is correct because glucose is a product, not a reactant, of photosynthesis.

Photosynthesis is a chemical reaction that occurs in plants which produce their food in the form of glucose by trapping the light energy from sun and using reactants such as carbon dioxide from the atmosphere and water. This process occurs in the leaf cells of the plants.

On the basis of the above information, this can be concluded that Jamila is correct because glucose is a product, not a reactant, of photosynthesis.

Gene Expression is the progression wherein the information from a gene is used in the combination of a functional gene product. In eukaryotic cells, genes are delimited by repressors as well as by transcriptional activators. The repressors will muddle to the specific DNA sequences and will constrain transcription.

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function.

The protein involved in the elongation of Bacillus anthracis to form its typical shape is unknown. However, the shape of a protein is critical to its function. For example, in the process of biological nitrogen fixation, the carrier protein leghemoglobin binds with a very high affinity to its substrate oxygen at a specific region of the protein where the shape and amino acid sequence are appropriate. If the shape or chemical environment of the active site is altered, the substrate may not be able to bind as strongly or not bind at all. Thus, for the protein to be fully active, it must have the appropriate shape for its function.

Answer:

Keratin is a protein.

Explanation:

Keratin is a fibrous protein that has the characteristics of rigid conformation, elasticity and impermeability to water. It has animal origin and is found in the vertebrate epidermis and in some epidermal appendages, such as hair, nails, hooves, feathers and scales. This protein is produced in cells called keratinocytes, which are the most abundant in the human epidermis.

Like any protein, keratin is made up of amino acids. It has a large amount of cysteine residues, which is responsible for 7% to 20% of the total amino acids present in keratin. Note that cysteine is mainly located in the terminal region of the keratin chains.

Finger contusion can be characterized by bruising of finger, where there is swelling and bleeding under the skin but no broken bones.

1. Diagnosis and Management:- Contusion of finger is diagnosed by the symptoms such as pain, swelling, discoloration, tenderness and difficulty in movement. Sometimes numbness is associated as swelling compresses the nerves in that region.X-ray (If required CT scan0 can be done to confirm the diagnosis and rule out fractures and other serious forms of injuries.

Depending upon the severity, treatment is decided. The contusion is managed with an aim to reduce pain, swelling and restore the movement. The options so as to treat the contusion, based on its severity are as follows

a. Applying Icepacks and keeping the finger propped up above the heart level.

b. Splinting and taping

c. Physiotherapy

d. Ultrasound therapy

e. Surgical treatment is required in case of torn ligaments.

These options of treatment are accompanied with over the counter pain killers and anti inflammatory drugs

Final answer:

Ligers, offspring of a tiger and lion mating, exhibit hybrid infertility due to hybrid sterility, which is a type of postzygotic reproductive isolation preventing them from reproducing.

Explanation:

The offspring produced between the mating of a tiger and a lion, a liger, which is unable to reproduce, is an example of hybrid infertility. Specifically, this is a case of hybrid sterility, which is a form of reproductive isolation that occurs after fertilization, resulting in a hybrid that is not capable of reproducing. Thus, the correct answer is c. hybrid infertility.

The biodiversity of the Earth’s vegetation makes up its beauty especially the grassland which is covered mostly of trees and grasses.  There are a lot of varieties of grassland and among of which is savanna grassland where we can find perennial grasses and the flowering plant called forbs.

The term mitosis does not apply to prokaryotes since, it involves nuclear division and eukaryotic structures.

ATP synthase uses a proton gradient to restore ADP to ATP in a process known as chemiosmosis, which takes place during oxidative phosphorylation.

The process by which ATP synthase uses a proton gradient to restore ADP back to ATP is called chemiosmosis. This occurs during oxidative phosphorylation, a key part of cellular respiration where the energy stored in the electrochemical gradient, developed due to the movement of protons (H+), is utilized. As protons flow through ATP synthase, much like water flowing through a turbine, they provide the energy needed for the enzyme to catalyze the production of ATP from ADP and inorganic phosphate (Pi).

AraC protein certain to the ara operator works as a repressor that avoid transcription of the same ara operon and the araC gene AraC protein is an activator in the presence of arabinose and repressor in the absence of arabinose -With arabinose absent, the AraC protein stays as
a homodimer. One AraC protein put together to the ara initiator and the other protein now binds to a different regulatory site in DNA called the ara operator.

Answer:

c

Explanation:

Following precautions should be taken when constructing;

1)      Contractors should know about the temperature on the work site.

2)      The unsatisfactory decision of safety measure strategy will crumple the particular undertaking quality.

3)      There should be the availability of LP gas heaters and blowers.

4)      Temporary workers can likewise pick poly fenced in area installed with platform frameworks firmly.

5)      Warmth conveying punctured texture tube running under platform will be utilized.

6)      There should be the utilization of dry mortar rather than wet mortar in winter season.

7)      Quick setting mortar or cement Mortar setting admixtures can be utilized.

8)      Wind should be above 25mph in wind barriers and the temperature that is required is below 25 degree.

Answer:

The correct answer is Y - glucose, Z - oxygen

Explanation:

In photosynthesis, plants- and also other organisms- take carbon dioxyde (CO₂), water (H₂O) and light (which is absorbed by chlorophyll pigments, those give plants their green color), and they convert inorganic materia in organic materia (chemical energy) in form of sugar. The overall process is described by the following global equation:

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → glucose + oxygen

In the diagram, the equation is:

carbon dioxide + water + sunlight → glucose + oxygen

Answer:

The correct answer is A.

Explanation:

Y represents Glucose, a product of cellular respiration. Z represents Oxygen, which is also a product of cellular respiration.

(CO2 + Water + Sunlight = Glucose and Oxygen)

3. Proteins

Explanation:

Enzymes are naturally occurring groups of organic substances of protein origin (they can be form by 62 amino acid residues, such as 4-oxalocrotonate tautomerase enzyme monomer to 2500 residue size) with intra or extracellular activity that have catalyst functions. This is achieved by lowering the activation energy to allow a chemical reaction, resulting in an increased reaction speed and allowing the metabolism of living things. Importantly, although most enzymes are proteins, there are also enzymes consisting of RNA as ribozymes.
