Answer:
The movement of Xylem is unidirectional and phloem is bidirectional
Explanation:
The tension created by transpiration “pulls” water in the plant xylem, drawing the water upward in much the same way that you draw water upward when you suck on a straw.
Phloem transport is bidirectional because sucrose gets accumulated in the phloem tissue and absorbs water creating a high turgor pressure. ... Hence the water flows from regions of high turgor pressure to low turgor pressure and the direction can be upwards or downwards from the leaves based on the gradient.

I believe the answer is white blood cells
When a foreign substance enters the body, foreign substance-specific proteins produce white blood cells (WBC). Hence, option C is correct.
What are white blood cells?The immune system of the body includes white blood cells. They support the body's defenses against illness and infection. Granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes are different types of white blood cells (T cells and B cells).
Blood is filtered and monitored by the thymus. T-lymphocytes, a type of white blood cell, are produced by it.
White blood cells (WBCs) defend against bacterial, viral, fungal, and other pathogen infections (organisms that cause infection). The neutrophil is a significant kind of WBC. These cells are created in the bone marrow and circulate throughout the body in the blood. Hence, option C is correct.

What does it mean to ‘translate’ something? What is being translated in protein synthesis?
Answer:
Answer:
Translation is the process of translating the sequence of a messenger RNA molecule to a sequence of amino acids during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding amino acid sequence that it encodes.

explain how carbon atoms can move to co2 in the air into an organic molecule inside a plant and then back to co2 in the air
Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.

In skin, the cells of the epidermis connect to the basal lamina through cellular junctions known as hemidesmosomes. Select the cytoskeletal element that helps maintain the integrity of this connection. intermediate filaments both intermediate microtubules and microfilaments microfilaments only microtubules only
Answer:
The correct answer is ''intermediate filaments.''
Explanation:
The intermediate filaments are made up of thick and resistant protein fibers, with an intermediate thickness between that of the microfilaments and that of the microtubules. They provide mechanical resistance to the cell, avoiding the rupture of the membranes of the cells subjected to stress. The macromolecules that make up the basal lamina interact specifically with specific receptor proteins present in the plasma membrane of the cell base, which in turn interact in the cytoplasm with filaments of the cell cytoskeleton. When the junction is associated with intermediate filaments, it is a hemidesmosome and when it is the actin cytoskeleton that is anchored in the junction, it is focal contacts. Hemidesmosomes are formed by a dense plate attached to the cell membrane, in which the intermediate filaments are inserted by joining connection proteins, such as desmoplakin, which connect to the cytoplasmic portion of the integral proteins of the cell membrane, which belong to the family of integrins.

Compared to the inertia of a 1-kilogram mass, the
inertia of a 4-kilogram mass is
A. 16 times as great
B. 1/16 as great
C. 1/4 as great
D. 4 times as great
please help.
Answer:
D. 4 times as great
Explanation:
The inertia of an object is the resistance offered by the object to change in its motion or position.
Then concept of inertia is obtained from Newton's first law of motion which states that an object which is not subjected to any net external force will remain its position of rest or constant velocity of motion until some net external force acts on it. The object at rest will then start to move whereas the object moving at constant velocity will experience a change in its speed or direction of motion.
This reluctance to change position is greater, the more massive an object is as well as the higher the speed of motion of the object. Thus, inertia is directly proportional to the mass of the object as well to the velocity of an object in motion.
From Newton's first law, inertia can be calculated as the force to be overcome to mobile an object, i.e. Inertia = F = ma
Where m is mass of object, a = acceleration of the object.
Objects on the earth's surface experience a constant acceleration, g.
Thus for a 1 kg mass, Inertia = 1 × g
For a 4 kg mass, inertia = 4 × g
The inertia of a 4 kg mass is four times as great as a 1 kg mass.
The inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great
Inertia is the property of matter that resists changes in motion. Mass is the quantitative matter of motion.
Mass is that quantity that is solely dependent upon the inertia of an object.The more inertia that an object has, the more mass that it has.A more massive object has a greater tendency to resist changes in its state of motion.Thus, the inertia of a 1-kilogram mass, the inertia of a 4-kilogram mass is - D. 4 times as great.

Explanation:
Compute the age of a basalt rock sample from the Moon containing 6 grams of Uranium-235 (parent isotope) and 42 grams of Lead-207 (daughter isotope). This rock is from a complex crater flooded with lava. The half-life of Uranium-235 is 704 million years.
Answer:
Age of rock = 21112000000 years
Explanation:
The half-life of a radioactive material is the time taken for half the original material to decay or it is the time required for a quantity to reduce to half of its initial value.
The ratio of parent isotope, Uranium-235 to daughter isotope, Lead-207 = 6 : 42 = 1 : 7
This means that for every one gram of the parent isotope, there are 7 grams of the daughter isotope. So,the quantity of radioactive material left is one out of eight its original value.
Number of half-lives undergone for 1/8 of the original value to to remain is given below:
1/8 = 1/2 × 1/2 × 1/2
Therefore, number of half-lives = 3 half-lives
Age of rock = half-life of Uranium -235 × number of half-lives
The half-life of Uranium-235 is 704 million years = 704000000
Age of rock = 704000000 × 3
Age of rock = 21112000000 years
