Answer:

B. Are the insect’s antennae longer than its head?

Explanation:

Dichotomous key refers to the tool or method which helps the scientist to identify organisms.

It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.

Example of a simple dichotomous key is shown below.

Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.

happy to help ya:)

The statement B is correct. Are the insect’s antennae longer than its head?

A dichotomous key is an important scientific tool, used to identify different organisms, based the organism's observable traits. Dichotomous keys consist of a series of statements with two choices in each step that will lead users to the correct identification.

Moreover, for example, in tree identification, a dichotomous key might ask whether the tree has leaves or needles. The key then directs the user down one list of questions if the tree has leaves, and a different question list if it has needles.

Therefore, dichotomous keys are useful for biological classification as well as identification. The word dichotomous is derived from the Greek words meaning “two parts.” Each step in the key provides two contrasting choices about a characteristic.

Explanation:

1) análisis de datos de ondas sísmicas

Evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.

There are various layers on the earth with distinct significance, such as the crust and the upper part of the mantle, which make up the lithosphere, which is the solid part of the Earth, and the tectonic plates that are constantly moving and colliding, which causes earthquakes and volcanic activity. The core is the inner part that has the magnetic fields, and the mantle is the part present in between the crust and the core.

Hence, evidence has led scientists to conclude that there are different layers within Earth's interior based on analysis of earthquake wave data, measurements of Earth's diameter, and temperatures taken within each layer, so options 1, 2, and 4 are correct.

Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.

Explanation:

The following are the shared core processes shared by all eukaryotes.:

1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.

2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.  

The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the  carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.

Answer:

Length of the real cells = 7500 cm

Explanation:

A scale model is a physical representation of an object that has the same aspects as that of the object.

A scale model can be used in fields like engineering, film making,  salesmanship, etc

Length of the student's cell model = 15 cm

The scale is [tex]1:500[/tex]

So,

Length of the student's cell model / Length of the real cells  = [tex]1:500[/tex]

15 / Length of the real cells  = [tex]1:500[/tex]

Length of the real cells  = 15 × 500 = 7500 cm

Answer:

7500 cm

Trees are classified into the category of renewable resources. Thus, the correct option is D.

A renewable resource may be defined as an energy source that cannot be depleted and are able to supply a continuous source of clean energy.

Coal, gemstones, and metals are classified into the category of non-renewable resources because they can be depleted and do not available for longer times. They are utilized as time passes.

Option A

Explanation:

The endocrine system and the excretory system works hand in hand in maintained thé functions of the body and in this context that kidneys. The hypothalamus functions in monitoring the amount of electrolytes in the blood and an increase in this amount indicates dehydration among others, whose cause might be s a result of low water intake, too much sweat etc. Detecting this, the hypothalamus signals for the secretion of antidiuretic hormone which moves to the kidneys and stimulate the organ to reabsorb more water. This hormone is transferred to and released by the pituitary gland all these being part of the endocrine system.

Tricuspid valve  is the path of blood through the heart and lungs

Explanation:

Blood is also responsible for transiting the blood and nutrients. The blood reached right atrium and from here it reached the right ventricles with the help of tricuspid valve. When the ventricles are full it closes to stop blood from going back to the atrium.

The inferior and the superior vena cava let the blood enter through them. The heart left the blood with the help of pulmonary valve to the pulmonary artery and the blood reached the lungs.  

Answer: I believe that the answer is that the population is evolving

Explanation: I hope that this helps

In Hardy-Weinberg equation, If biologists can show that either p or q is changing over a period of time, the population is decreasing in size.

The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium, model, theorem, or law, states that allele and genotype frequencies in a population will remain constant from generation to generation.

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors.

For populations in the Hardy-Weinberg equilibrium, the equation connects allele frequencies to genotype frequencies. This equation allows us to compare a population's genetic structure in reality over time to the expected genetic structure.
