The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25  

0.75≤t≤3.25

The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.

To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.

We can start by setting the equation for the rocket's distance above the ground level equal to 3200:

We can then solve this equation for t using the quadratic formula

[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]

Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

This is because immunization programmes are programmes organised by the government to prevent some certain diseases by boosting our immune system to prevent them through vaccines.

Theses programmes for infants include DPT, measles, poliomyelitis, BCG and MMR.

(ii) For childre include TT, small pox, DTTyphoid, and TAB.

(iii) For pregnant woman it include TT and hepatitis-B.

Answer:

DNA is pivotal to our growth, reproduction, and health. It contains the instructions necessary for your cells to produce proteins that affect many different processes and functions in your body. Because DNA is so important, damage or mutations can sometimes contribute to the development of disease.

Short for deoxyribonucleic acid. The nucleic acid that is the genetic material determining the makeup of all living cells and many viruses. ... An example of DNA is the chain of basic materials in the chromosomes of the human cell.

Explanation:

Answer: Chromosome pairing refers to the lengthwise alignment of homologous chromosomes at the prophase stage of meiosis. ... For these organisms to produce cells with a single set of chromosomes, the sets have to be separated such that the daughter cells have one copy of each chromosome. The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.

Explanation:

The way the REE changes how a person ages is through the reduction in fat-free mass.

This refers to the metabolism of the body that occurs when the body is at rest, due to homeostasis and biological equilibrium.

Hence, other factors that can lead to the aging process of a person based on this resting energy expenditure (REE) are the decrease in muscle mass, in relation to FFM and also the decrease in tissue metabolic rates.

Answer:

C. Aerobic respiration

Explanation:

Aerobic respiration occurs when oxygen is present

Anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration is usually associated with fermentation process (eg Alchohol production)

The main difference between aerobic and anaerobic respiration is that aerobic respiration needs oxygen to occur, while anaerobic respiration does not. Option C. Only aerobic respiration requires oxygen.

Aerobic and anaerobic respiration occurrence depends on the presence or absence of oxygen. Option C. Only aerobic respiration requires oxygen.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

This type of respiration occurs in the presence of free oxygen. It involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.

Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.

This is the type of respiration that occurs in the absence of free oxygen.

It is also a series of reactions by which the cell produces 2 ATP molecules by using pyruvate (product of glycolysis).

Anaerobic respiration can occur in two ways: lactic fermentation and alcoholic fermentation.

The whole anaerobic process occurs outside the mitochondria.

Options:

A). Only aerobic respiration involves fermentation. FALSE.

Anaerobic respiration involves fermentation.

B). Only anaerobic respiration occurs in the mitochondria. FALSE.

Aerobic respiration occcurs in mitochondria and anaerobic respiration occurs in the cytoplasm.

C). Only aerobic respiration requires oxygen. TRUE

Anaerobic respiration does not need oxygen.

D). Only anaerobic respiration produces carbon dioxide. FALSE

Alcoholic fermentation produces CO₂ too.

The correct option is C. Only aerobic respiration requires oxygen.

Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance.

Answer: D. force applied to the foot by the ball.

Explanation:

The basic premise of force is that for every action, there is a reaction. The reaction force is the force that pushes back so to speak, against the action that you initiated.

This reaction force by acting against us, ensures that we move forward by pushing us.

When the player struck the ball, the ball pushed back against the player and this force that was applied to the foot by the ball was the reaction force.

Answer:

Homologous structures.

Explanation:

Homologous structures provide evidence for common ancestry because the organs are similar in position, structure, and evolutionary origin in homologous but different in their function, while on the other hand, the analogous structures indicates that similar pressures on organisms can produce similar adaptations among organisms. so we can say that homologous structure provides evidence for a common ancestor of different organisms.

Order, Sensitivity and response to stimuli, Reproduction, Growth and developement, Regulation, Homeostasis. Hope that helps!

Reproduction is the process in making more of the same species. we won't get into that. Order is the food chain, and what the animal kingdom should cisist of. In sensitivity and response to stimuli,  organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch. Regulation is kinda like the ability to adapt. Animals come from all over, so they need to adapt to the climate, resources, and other animals around.
