When conducting a population sampling study, on the first capture attempt, we _______ the captured individuals.

deff fn [24]

When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.

<h3>What is the mark-recapture method?</h3>

This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.

Thus, option "D" is correct.

Use the key to identify each species. Write the letter of each species (A to G) in the correct

sveticcg [70]

Dichotomous keys are useful to identify organisms according to their morphological traits. The given key provides enough macroscopic morphological traits to identify these Arachnida species.

-----------------------------------------------

A dichotomous key is a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.

The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.

The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

In the exposed example, as the key provides morphological traits, we will separate the organisms into two groups:

the group that has the trait
the group that does not have it.

By recognizing each trait in each of the individuals, we will get to identify the species.

1

(a) Abdomen with a tail --------------------------- The only option is E

(b) Abdomen without a tail ---------------------- All the others A, B, C, D, F, G

2 ---Only for group A, B, C, D, F, G---

(a) Legs much longer than abdomen and cephalothorax ----------A and G

(b) Legs not much longer than abdomen and cephalothorax----- B, C, D, F

3 ---Only for group A, G---

(a) Hairs on the legs -----------------------------------The only option is A

(b) No hairs on the legs ------------------------------ G

4 ---Only for group B, C, D, F---

(a) Cephalothorax or abdomen segmented ----------------The only option is D

(b) Cephalothorax or abdomen not segmented ----------- B, C, F

5 ---Only for group B, C, F---

(a) Abdomen and cephalothorax of the same size --------The only option is F

(b) Abdomen and cephalothorax of different size -------B, C

6 ---Only for group B, C---

(a) Body covered with long hair ----------------------------------The only option is C

(b) Body not covered with hair ------------------------------------B

A → Tegenaria domestica

B → Ixodes hexagonus

C → Tyroglyphus longior

D → Chelifer tuberculatus

E → Abaliella dicranotarsalis

F → Poecilotheria regalis

G → Odielus spinosus

In what ways do you think climate change will impact the water cycle

vampirchik [111]

Answer:Climate change intensifies this cycle because as air temperatures increase, more water evaporates into the air. Warmer air can hold more water vapor, which can lead to more intense rainstorms, causing major problems like extreme flooding in coastal communities around the world

What is osmolarity? Hemopoiesis?

Andrej [43]

Answer:

Osmolarity:

Osmolarity may be defined as the number of solutes dissolved in per solution of liters. The osmolarity plays an important role in the human body as it maintains the water electrolyte balance in the body. The osmolarity of the human plasma is about 275-299 milli-osmoles/kilogram.

Hemopoiesis:

Hemopoiesis may be defined as the process of formation of blood cells in the body. The main types of blood cells formed during this process are red blood cells, white blood cells and platelets. The hemopoiesis majorly occurs in the bone marrow cells.
