Use the drop-down menus to complete the statements. A vertical column of elements in the periodic table is called a ____ . A horizontal row of elements in the periodic table is called a ____ . Atoms of elements in the same group have the same ____ . As you move from left to right on the periodic table, the atomic number ____ .

Answers

Answer:

1) group

2) period

3) numbers of valence electrons

4) increases

Explanation:

When we move in a periodic table from top to bottom or vice versa along a vertical column , it is said that we are moving along a "group" in a periodic table.

Like wise when we move in a periodic table from left to right or right to left in a horizontal row , it is said that we are moving along a "period" in a periodic table.

The classification of elements belonging to any specific group of periodic table is dependent on the total number of valence electron. All elements of with in a group have same number of valence electrons however, the orbitals may change.

The atomic number increases while moving from left to right as the number of orbitals in which the valence electron is found also increase in the same direction.

A vertical column of elements in the periodic table is called a group

A horizontal row of elements in the periodic table is called a period

Atoms of elements in the same group have the same numbers of valence electrons

As you move from left to right on the periodic table, the atomic number increases

1) group

2) period

3) numbers of valence electrons

4) increases

Why is RNA necessary to act as messenger?

Answers

To send instructions given by DNA to the rest of the body.

Because it is the one on which the DNA info is copied, and then it goes to the ribosome and brings him the "map" to synthesize the proteins encoded in your DNA.

Choose the equation that represents an exponential function that passes through the point (2, 36).A. f(x) = 4(3)x
B. f(x) = 4(x)3
C. f(x) = 6(3)x
D. f(x) = 6(x)3

Answers

Since we were given only one point, we have to test each exponential function for the point $(2,36).$

Since exponential functions are of the form $y=n(a)^(kx)$ , The correct option is between option A and option C.

For option A,

$f(x)=4(3)^(x)$

On substitution, we have;

$36=4(3)^(2)$

$\Rightarrow 36=4* 9$

$\Rightarrow 36=36$ .

Since the point satisfied the exponential function $f(x)=4(3)^(x)$ , the exponential function goes through it.

Hence the correct answer is option A.

No need to test for option C again.

Answer:

a is right

Explanation:

Roundworms have mechanoreceptors called _____ on external bristles.A. tentacles
B. setae
C. nephridia
D. whiskers

Answers

In the sentence "Roundworms have mechanoreceptors called _____ on external bristles", the word that correctly completes the sentence is B. setae. Roundworms or nematodes are a diverse animal phylum. The main sense organs of roundowrms are setae, papillae, and amphids. They use setae as mechanoreceptors to detect motion.

setae is the right answer
