Answer: Police officer who allows selected people to enter and leave.

The cell membrane acts as the protective covering of the cell. This membrane is selectively permeable.

The membrane which is selectively permeable that allows only certain molecules to pass through it. The smaller molecules and the non polar molecules are passed through this membrane.

The molecules such as sugar and protein are not allowed to pass through the selectively permeable membrane.

In this way the cell membrane acts as policeman that allows the movement of selected people only.

Which shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the
iogann1982 [59]

Answer:

The correct answer is option d) "head-on".

Explanation:

In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

1.What taxon (classification levels) are represented by the scientific name of an organism? What are the rules for writing the s
Ksivusya [100]

<u>Answer</u>:

1.a) Species. It is the lowest taxon and represents the scientific name of the organism.

b) The species name is part of the binomial system of nomenclature developed by Linnaeus.

Thus it is composed of two parts each with its own writing rules (ex. gray wolf - <em>Canis lupus</em>):

A. the genus or generic name

- written first

- always underlined or italicized

- the first letter is always capitalized

ex. <em>Canis</em>

B. the specific epithet or species name

- is written second

- always underlined or italicized

- never capitalized

ex. <em>lupus</em>

<em />

2. The results should always be the same. A dichotomous key is an identification tool based on a series of choices between alternative characters (dichotomous = divided into two parts). Thus, there is no room for subjective observation that may lead to another result. If the morphological traits of the organism are correctly identified, the the result should always be the same. Any differences occur due to errors on the scientist's part.

During the late cretaceous, the bisti badlands were home to numerous animals including turtles, crocodiles, and even dinosaurs.
vaieri [72.5K]
These animals were living in an environment with a warm climate that results in changing sea levels. These conditions create a lot of shallow inland seas allowing these animals to thrive. The Cretaceous period is the last period of the Mesozoic area where new groups of mammals, birds, and flowering plants appeared on Earth.

Luden [163]

Answer:

The correct option is A. Polycythemia Vera

Explanation:

Polycythemia vera is a myeloproliferative disorder of bone marrow hematopoietic cells that causes excessive production of all types of blood cells.

Primary erythrocytosis occurs as a result of polycythemia vera, in this myeloproliferative disorder the bone marrow produces too many red blood cells along with excessive amounts of white blood cells and platelets. Bone marrow under normal conditions produces blood cells and contains the precursor cells of the three series: red blood cells, white blood cells or leukocytes and platelets or thrombocytes, this disorder is characterized by excessive or uncontrolled proliferation or growth of these cells. The increased production of red blood cells or erythrocytes is called erythrocytosis.
