Which method to determine population size is the least invasive

Answers

It seems that you did not provide possible answers, but the mark recapture method is one method that is not very invasive. The population size is estimated by marking a certain number of individuals and releasing them into the wild, followed by a second capture later on. The members captured the second time with the markets from the original capture are used to estimate population size in the formula s*n/x where s and n are the first and second captured population sizes and x is the number of marked inidividuals from the second capture.

A root is absorbing water from the soil. Which route will the water travel inside the root? A. Cambium --> phloem --> xylem --> stele --> endodermis --> cortex --> epidermis/// B. Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium ///C. Epidermis --> cortex --> endodermis --> stele --> xylem --> phloem --> cambium

Answers

The router through which water will travel inside the root is Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer you were looking for and it has helped you.

Answer:

Option B, Xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium ///

Explanation:

The start of water transportation via roots takes place through the Xylem as these are the specialized cell in roots to intake water from the ground. These cells are arranged in the form of layer and filters the water before transporting. After the filtration in Xylem, water then passes to phloem (which are also part of conducting system of plants and runs parallel to the xylem). After the phloem,  water then goes to the central part of the root which is known as stele and then it reaches the epidermis. From epidermis , absorbed water then goes to the cortex of other tissues and organ and finally it  reaches the cambium.

Hence, option B is correct

According to the Big Bang theory of the origin of the universe, the universe has expanded from a hot dense state into a vast, cooler state. What would be considered scientific evidence supporting this theory?A) Galaxies are moving toward each other.
B) Galaxies are moving away from each other.
C) Cosmic background X-ray radiation was detected in space.
D) The existence of common elements throughout the universe.

Answers

The correct option is option B, Galaxies are moving away from each other

It was discovered by Edwin Hubble in 1920, that galaxies are moving away from each other in proportion to the distance between them. The greater the distance at which a galaxy  exists, the faster is the distance with which it is moving away. Hubble established the Hubble’s constant which establishes expansion rate which is also helpful in determining the age and size of the universe.

In 1953, who developed the model that is shown below?

Answers

There is no attached model, but the greatest discovery in biology in 1953 could be only the discovery of DNA double helix. Watson and Crick discovered the chemical structure of DNA molecule. They showed that the molecule is looked like twisted ladders, and described it as a double helix. Their discovery was the great basis for a development of modern molecular biology.

Answer:

A: James Watson and Francis Crick
