Multicellular plants had to develop a _____ system to move nutrients around its body.

BRAINLIEST AND 25 POINT COME BEFORE ITS TO LATE

MAVERICK [17]

Answer:

Frequency: The rate that sound or other waves vibrate at

Frequency: The rate at which something happens

wavelength: wavelength -- the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave

wavelength: wavelength -- a shared orientation leading to mutual understanding; "they are on the same wavelength"

energy: Power that makes machinery work

energy: The physical and mental effort used to do things

Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves.

Reflection: A reflection shows what something is like

Reflection: The image that reflected from or in something

Refraction: refraction -- the change in direction of a propagating wave (light or sound) when passing from one medium to another

Refraction: deflection, deflexion, refraction -- the amount by which a propagating wave is bent

Absorption: absorption, soaking up -- a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid

Absorption: absorption -- the physical process in which incident radiated energy is retained without reflection or transmission

Absorption: concentration, engrossment, absorption -- complete attention; intense mental effort

Absorption: preoccupation, preoccupancy, absorption, engrossment -- the mental state of being preoccupied by something

Absorption: assimilation, absorption -- the absorbing of one cultural group into harmony with another

3 States of Matter: There are three very well-known states of matter: Solids, Liquids, and Gases.

Categories of Biodiversity: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.

Answer:

Although the data in the question is not clearly stated, the correct date is stated in the image attached to this answer and it is also stated below

What is the sample variance of the following data, which describe the height growth of 10 foxtail pine trees grown in a common garden ( give your answer to one decimal place)?

Tree Height(cm)

1 25.6987

2 19.6587

3 11.4780

4 9.11130

5 16.8747

6 14.7771

7 33.0001

8 24.0000

9 19.4441

10 14.1010

answer 51.9

Explanation:

what is a sample variance?

A sample variance (denoted as $S^{2}$ ) is used to calculate how far a set of numbers are from the mean value of the set. Mathematically, it is defined as the average of the squared deviations from its mean value.

Let the individual value of the trees be represented as x₁ to x₁₀

Let the total number of Foxtail pine trees be N

To calculate the standard deviation, we will first calculate the mean or average of the height of the trees

1. Mean (μ) = $\frac{x_{1}+x_{2}+x_{3}+x_{4}+x_{5}+x_{6}+x_{7}+x_{8}+x_{9}+x_{10} }{N}$

= $\frac{25.6987+19.6587+11.4780+9.11130+16.8747+14.7771+33.0001+24.0000+19.4441+14.1010}{10}$ = $\frac{188.1437}{10} = 18.8144$

2. we need to calculate the sum of the squares of the individual deviations.

∑[x-μ]²= $(25.6987-18.8144)^{2}+(19.6587-18.8144)^{2}+(11.4780-18.8144)^{2}+(9.11130-18.8144)^{2}+(16.8747-18.8144)^{2}+(14.7771-18.8144)^{2}+(33.0001-18.8144)^{2}+(24.0000-18.8144)^{2}+(19.4441-18.8144)^{2}+(14.1010-18.8144)^{2}=466.8786$

3. Now the variance is ; (∑[x-μ]²) ÷ (N-1) and since N=10, then N-1 = 10-1 = 9

= $\frac{466.8786}{9} = 51.8754.$

we were asked the give our answer to one decimal place

∴ Variance( $S^{2}$ )= 51.9

Compared to arteries, the velocity of flow of the blood through the capillaries is:______.

Nutka1998 [239]

Answer: D) much slower

Explanation:

The circulatory system, made up of arteries and veins, is fundamental to maintaining life. Its function is the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of physiological pH, and the mobility of the elements, proteins, and cells of the immune system. An artery is each of the vessels that carry blood with oxygen from the heart to the capillaries of the body. They arise from a ventricle and their walls are very strong and elastic to resist the pressure that the blood exerts when it is pumped out of the heart.

Capillaries are very small diameter, thin-walled blood vessels connect small arteries (arterioles) to veins, allowing nutrients and oxygen to pass through to tissues. The main function of the capillaries is the exchange of substances between the light of the capillaries and the cell interstice of the tissues.

When the blood reaches the capillary bed, the speed with which it circulates inside these vessels is very low. This is due to the fact that in a branching system of tubes, the speed decreases proportionally to the increase in the joint section of the branches. Thus, in the aorta, which has a small section, the speed is very high (400 mm/sec), it decreases at the level of the arteries and arterioles and at the capillary level it becomes minimal (0.1 mm/sec). This fact, together with the thinness of the capillary wall, provides the necessary conditions of time and space for the exchange to take place in the most optimal way.
