Answer:
The correct answer is - A. It stimulates the production of other gland's hormones.
Explanation:
The pituitary gland is also known as the "master" gland of the endocrine system. It stimulates or regulates other glands and the secretion of hormones of many of the other endocrine glands.
Its ability to control the function of the other glands and hormones gives it its name of master gland. The size of this gland is like a pea and found at the base of the brain.

How do clastic rocks get different sizes of particles?
Answer:
Such material, called detritus, consists of fragments of rocks and minerals. When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation. This type of sedimentary deposition is referred to as clastic sedimentation.

Explanation:
Genetic diversity is ultimately/mainly the result of _______________
A. meiosis.
B. viruses.
C. mutations.
D. reproduction.
Answer:
A. meiosis.
Explanation:
Meiosis is one of the two major types of cell divisions in living organisms. Meiosis is the process by which four daughter cells that are genetically different from the parent cell are produced. Meiotic process is carried out solely during sexual reproduction to yield gametes or sex cells.
The gametes have their chromosomal number reduced by half during the process. However, one immense importance of meiosis is that it PROMOTES GENETIC DIVERSITY. A process called crossing over, which is the exchange of chromosomal segment between non sister chromatids, makes this possible.
How is biodiversity impacted by palm oil plantations?Palm oil plantations provide habitats to several species, so they do not cause habitat fragmentation.Palm oil plantations have fewer habitats, niches, trophic levels, and communities, resulting in a weak ecosystem.Without global extinction, species extirpation has little impact on its ecosystem in palm oil plantations.Removal of predators in palm oil plantations promotes survival of other species and therefore species diversity.In palm oil plantations, only one tree species and few canopy plants are allowed to grow.
Answer:
Palm oil plantations have lesser habitats, communities, trophic levels, and niches that result in weak ecosystems.
Explanation:
Oil palm plantation is a crop that is high in demand for the extraction of palm oil used for various purposes like the formation of soaps, cleaning products, washing powder, and production of food products.
Oil palm plantation is mainly responsible for deforestation, pollution, and habitat fragmentation. Trees are grown at a particular distance and neighboring other species are removed so that the palm trees receive the nutrients from the soil and it will also facilitate easy harvest. Only one tree species is palm tree allowed to grow and other species are restricted as they can mask the sunlight by their canopy making it unavailable for oil palm plants.
Thus due to habitat fragmentation involving discontinuity in an organism's preferred environment of survival fewer habitats of species can be found as few species which can inhabit the oil palm plants can survive, and the ecosystem becomes weak. As the species are interdependent on each other for food needs. The low number of plant species will reduce the population of faunal species from the location. The functional roles or niches are affected by species, the whole biotic community or ecosystem gets disturbed. This will reduce the population of the species and reduce the overall biodiversity of a region.

Reason why two species of plant cannot interbreed because their flowers differ in size and shape and require pollination by different species of bee
Answer:
Due to difference in size and shape of flower.
Explanation:
Two species of plant cannot interbreed with each other because their flowers differ in size and shape. Each flower has different time of maturation and the appearance of reproductive stage as well as difference in their chromosome number. If these factors occurs on the same time and having same number of chromosomes so they are able to interbreed with each other otherwise not so that's why we can say that two species can't interbreed with each other.

Answer:
time: 1.122 secondsrange: 10.693 mmaximum height: 1.543 mExplanation:
Given:
runner is launched at 30° angle to horizontal at 11 m/s
acceleration due to gravity is g = -9.8 m/s²
Find:
runner's hang time
runner's distance to the landing point
runner's maximum height
Solution:
The (horizontal, vertical) speed components will be ...
(11 m/s)(cos(30°), sin(30°)) = (5.5√3 m/s, 5.5 m/s)
The time of flight can be found from the height formula:
h(t) = 1/2gt² +vt . . . . . . where v is the vertical speed at launch
The time we're concerned with is the time when h(t)=0 and t>0.
0 = -4.9t^2 +5.5√3t = t(-4.9t +5.5√3)
The second factor is zero when ...
t = (5.5√3)/4.9 ≈ 1.122 . . . seconds hang time
__
The distance to the landing point will be the product of horizontal speed and hang time:
d = (5.5 m/s)(5.5√3/4.9 s) ≈ 10.693 m . . . . distance to landing
__
The maximum height can be found from the formula (based on conversion of kinetic energy to potential energy) ...
h = v²/|2g| = (5.5 m/s)²/(2(9.8 m/s²)) ≈ 1.543 m . . . . maximum height

CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical
Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.
What does topography show?
Answer:
I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.
II. The shape of the land.
Explanation:
In Geography, topography can be defined as the shape and structure of the Earth surface. Thus, a topographic map is used to graphically describe this features.
A topographic map can be defined as an accurate and detailed graphical (two-dimensional) description, representation or records of both natural and man-made (artificial) features on the surface of the Earth.
A topographic map is a two-dimensional model that uses contour lines to represent points of equal elevation above sea level such as mountains, hills, plains, valley etc.
The two-dimensional model of a topographic map graphically represents the height of a mount and the steepness of a slope through the use of contour lines.
Contours can be defined imaginary lines used for connecting locations that are having similar elevations on the Earth's surface.
Hence,a topography show two (2) main things and these includes;
I. The landforms such as valleys, volcanoes, hill, plateau, etc., in a geographical area or region.
II. The shape of the land.

Four differences between the aorta and vena cava ?
Answer:
Aorta and vena cava are two main types of blood vessels attached to the heart. The main difference between aorta and vena cava is that aorta carries oxygenated blood whereas vena cava carries deoxygenated blood. Aorta is the main artery that leaves the heart through the left ventricle. It supplies oxygenated blood throughout the body. Two types of venae cavae supply blood to the right atrium of the heart. They are superior vena cava and inferior vena cava. Superior vena cava drains deoxygenated blood from the head, arms, and other upper parts of the body while inferior vena cava drains that from the lower parts of the body.
