Which level of taxonomy divides its organisms based on DNA sequencesinstead of structural similarities? *
A Domain
B Kingdom
C Genus
O D Species

Answers

Answer 1

Answer:

D Species

Explanation:

Living organisms have been organized into groups using the Kingdom to Species classification. Kingdom level represents the least specific while Species level represents the most specific. Prior to the discovery of DNA, classification of organisms has been based on structural similarities i.e. organisms that look similar are classified into the same species.

However, the discovery of DNA, put a stop to the erroneous classification of organisms based on structural similarities as there were many exceptions to this. Since members of the same species have a nearly identical DNA, it is used to divide its organisms based on DNA sequences

instead of structural similarities.

After the rain of 12th june 2017 an ecologist measured a volume of 1414cm cube of rain water from a rain gauge wish a funnel diameter of 24cm. Calculate the mm of rain that fell that day

Answers

Rainfall is measured as depth on the surface of the Earth, typically in mm. We know the volume of water in the rain gauge: 1414 cubic centimetres. We know need to know the area of the Earth that this volume fell on. This would be the area of the funnel opening that points up to the sky to catch the rain. We know the diameter is 24 cm. So we need to determine the area of a circle with a diameter of 24 cm. The equation to use is: area = pi * radius^2. Since the radius of a circle is half the diameter, the equation is:
So area is 3.14159 * 12^2
= 452.39 cm^2Volume = depth * areadepth = volume/areadepth = 1414/452.39= 3.13 cm = 31.3 mm

Adipose tissues belong to ___________a. nervous tissues
b. muscle tissues
c. connective tissues
d. epithelial tissues

Answers

Answer:

c. connective tissues

Explanation:

Adipose tissue is a connective tissue which is composed of cells called adipocytes. Since it a loose connective tissue located beneath the skin and around internal organs.

The main function of this tissue is to store fat, although it also cushions and insulates the body. It provides protective covering around internal organs. Since it stores fat it also functions as a reserve of nutrients.

Adipose tissue also acts as an endocrine organ. It has the ability to make a number of biologically active compounds that regulate metabolic homeostasis.

Explanation:

) How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?

Answers

Answer:

$5 * 10^(10)$

Explanation:

The question is not complete. Remaining part of the question is as follows - Minimal growth medium for bacteria such as E. coli includes various salts with characteristic concentrations in the mM range and a carbon source. The carbon source is typically glucose and it is used at 0.5% (a concentration of 0.5 g/100 mL). For nitrogen, minimal medium contains ammonium chloride (NH4Cl) with a concentration of 0.1g/100 mL

How many cells can be grown in a 5 mL culture using minimal medium before the medium exhausts the carbon?

Solution -

We will first find the mass concentration of 0.5 g/100 mL of solution.

$(0.5)/(100)$ gram per ml of glucose
