Answer:

binding specificity; affinity

Explanation:

Receptor binding specificity can be defined as the selectivity of a receptor to bind with a particular chemical messenger. Binding specificity is determined by the interaction between the chemical messenger and its specific receptor, as well as the binding site three-dimensional (3D) structure of both. This concept is contrary to receptor promiscuity, where a receptor can bind to many different chemical messengers. On the other hand, binding affinity can be defined as the overall affinity or avidity of binding. The binding affinity is determined by the accumulated strength of individual attractive forces between a chemical messenger (ligand) and its receptor.

Answer:

Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

If AMOC and the Gulf Stream do become weaker, the probability is that Northwest Europe is going to get cooler, or not warm as much as it otherwise would under global anthropogenic climate change. And if sea level is a little bit higher, maybe because of the Gulf Stream weakening, it only makes matters worse.

Answer:

a. both oxygen and carbon dioxide

b. carbon dioxide only

c. carbon dioxide only

d. oxygen only

e. carbon dioxide only

f. oxygen only

g. oxygen only

h. oxygen only

Explanation:

This question is describing the gaseous exchange of carbon dioxide and oxygen that occurs during cellular respiration. The gaseous exchange occurs via a structure called ALVEOLI OR AIR SAC.

According to this question, the following statements in the question will be matched with whether it applies to oxygen only, carbon dioxide only, or both oxygen and carbon dioxide:

a. Both oxygen and carbon dioxide are diffused through the alveoli capillaries.

b. Carbon dioxide is the waste product of cellular respiration (excreted via the lungs).

c. Carbon dioxide have the ability to form carbonates (CO3²-) and are sometimes transported in that form.

d. Oxygen from the lungs diffuse into the alveoli during inhalation.

e. Carbon dioxide from the body tissues are carried by the blood into the alveoli in order to be transported out of the body.

f. Inhalation is the taking in of air (oxygen-containing). Hence, oxygen only enters alveoli during inhalation.

g. Oxygen is the necessary substance needed by cells in order to perform cellular respiration (aerobic).

h. Haemoglobin is an iron-based protein present in the blood cells. It possess affinity for oxygen and carries oxygen in the blood.

Answer: SW

Explanation:I got it wrong and it gives you the right answer so thats that

The direction of wind is SW direction. Hence option D is correct.

Wind is defined as the air movement brought on by the Earth's rotation and the sun's uneven heating of the surface. The uneven heating of the Earth by the sun and the rotation of the Earth result in wind, which is the movement of air. Light breezes to natural disasters like hurricanes and tornadoes are all types of winds. In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or polluting the environment.

An anemometer can measure wind speed, and a weather vane or wind vane can detect wind direction. When put with anemometers, many wind vanes can be installed in numerous locations to calculate the overall wind profile of a specific area.

Thus, the direction of wind is SW direction. Hence option D is correct.

Explanation:

changes from determination to interminate pathways molecular changes such as expression of certain genes for tissue specific protein.

Answer:

Based on knowledge of enzymes and the given data, it can be concluded that  Tcn-protease is most likely active in the alligator's stomach and Wx-protease is most likely active in the alligator's intestines. As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.

b. Nucleus

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;

1. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.

2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.

3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.

4. Chromosomes : they give sets of instructions for the synthesis of products.

5. Ribosomes : they are involved in the build up of proteins.

6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.

7. Cytoskeleton : they help to maintain and support the shape of the cells.

8. Vesicles : they ensure proteins are properly transported to the right and exact location.

9. Golgi apparatus : it prepares the protein for export by chemically tagging them.

10. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.

Hence, the principal site of protein synthesis in a cell is nucleus.

Answer: The remains of an organism that lived 500 years ago is called a fossil.

Explanation:

A fossil can be defined as dead remains of plants and animals that existed past geological era. The traces of bones, and other skeletal remains, pollen, hard wooden materials can be found in the compact rock as the soft parts of the organisms are decomposed and decayed. The remains like shells, exoskeleton, amber, hair, and other can also be found. It takes many years for the development of fossil beneath the earth crust. The morphological, anatomical, physiological and molecular features can be assessed to know the age of the fossil.

Answer:

fossil is any trace of prehistoric life

Answer:all life form contains more than one cell

Explanation: thats the only question that's not true

Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.

Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

Causing Jason's father to have a genotype of of Bb, B is dominant brown phenotype and b is recessive blonde phenotype, and since Jason's mothers genotype is recessive b the possible genotypes are Bb, Bb, bb, bb so Jason has a probability of 50%.

Answer:

DNA strand: TGCTCAGAC

Complementary DNA strand: ACGAGTCTG

Explanation:

Deoxyribonucleic acid (DNA) is a molecule consisting of two strands, where each strand is composed of a linear sequence of nucleotides (polynucleotide chain). Each DNA nucleotide is composed of 1-a deoxyribose sugar, 2-a phosphate group, and 3-a nitrogenous base. In DNA, there are four types of nitrogenous bases: Adenine (A), Guanine (G), Thymine, and Cytosine (C). These nucleotides are held together by hydrogen bonds in order to form the DNA double helix. By base pairing, G always pairs with C, and T always pairs with A, thereby the amount of G is equal to C and the amount of T is equal to A. In the RNA, T bases are replaced by Uracil (U) bases.
