malfutka [58]3 years ago
8 0

Answer:

It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.

Answer:

Observation

Curiosity

Determination

Explanation:

A biologist is a scientist that specializes in the study of biology or life generally. However, to become a successful biologist as stated in the question, the three mentioned characteristics needed are:

1. Observation- being an observer is key to becoming any scientist, including a biologist. Observation is the foundation of a scientific method i.e. it begins the process. Hence, a biologist must have good observation skills in order to thrive.

2. Curiosity- Curiosity refers to the ability to want to know what's going on. It's being inquisitive in order to learn new things. Asking questions is equally an important part of a scientific method as it determines the experiment. The question asked is what creates the experiment. Hence, being curious is a good quality for an intending biologist.

3. Determination: Being determined is not a quality only a biologist should possess. Determination is a must for any individual in any field. It is the ability to carry on irrespective of setbacks, which are inevitable.

From left to right, which is the sequence of the<br> complementary strand of DNA in this molecule?
ladessa [460]

Answer: Option A) A-C-T-T-G

Explanation:

The base sequence on a strand of DNA is usually paired to specific complimentary bases. These specific pairings are as follows:

Adenine (A) pairs with Thymine (T)

Guanine (G) pairs with Cytosine (C). So when you find A replace with T, so also replace C with G and vice versa.

Thus, the complimentary sequence of the T-G-A-A-C DNA strand is A-C-T-T-G
