What is true of intercellular signals that do not go through direct connections between cells, such as gap junctions?

Frogs have lungs for breathing, but they also absorb dissolved oxygen directly through their skin. This allows respiration to oc

alukav5142 [94]

Answer: B. Water breaks down into oxygen molecules for respiration.

Water is the required for photosynthesis, a process by which plants (terrestrial and aquatic) makes their food by utilizing water as a reactant to produce oxygen and glucose as product. The glucose act as a source of energy for conducting various metabolic processes in plants but oxygen is released in the air.

$6CO_2\ \ \ \ +6H_2O\rightarrow\ C_6H_{12}O_6+6O_2\\carbon\ \ \ \ water\ \ \ \ \ \ \ \ glucose\ \ \ \ \ \ \ oxygen\\ dioxide$

This oxygen is necessary for terrestrial and aquatic animals for respiration. Therefore, water breaks down into oxygen by the process of photosynthesis, hence water plays important role in respiration in living beings.

What is the acceleration of a marble in that has a mass of 90kg and a force applied of 60N

miskamm [114]

Answer:

0.6... or 3/5

Explanation:

To find the acceleration, we need to use the acceleration formula:

a=F/m

So all we have to do now is plug in the numbers:

a = 60/90

Once we divide 60 by 90, we will get the acceleration of the marble.

60/90 = 0.6... (repeating)

Our final answer should be:

0.6... or 3/5

Humans and baboon have noses with nostrils that face downward, but many other primates have noses with nostrils that face out to

Zepler [3.9K]

Answer:

a shared derived trait.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, weight, handedness, freckles, curly hair, hair color, blindness, complexion, height, etc.

All humans and baboons are created having noses with nostrils underneath i.e facing downwards but other primates such as platyrrhines have their nostrils facing sideways (face out to the side). Also, humans and baboons shared close similarities with each other when compared than they share with the primates having a outward-facing nostrils.

This ultimately implies that, both humans and baboons sharing the downward-facing nostril orientation is an example of a shared derived trait.

A shared derived trait can be defined as a trait or characteristic that is shared between two lineages and subsequently evolves leading up to a clade, which is a distinguishing feature from other species.

If one parent has type B blood and the other type O blood what percentage of the child's blood will be B, O, A?

kirill115 [55]

Answer:

If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.

Explanation:

Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.

Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.

Blood type A contains antigen A and its genotype can be A|A or A|O.
Blood type B contains the B antigen, whose genotype can be B|B or B|O.
Blood type AB contains both antigens and a single A|B genotypic expression.
Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.

Scenario 1: Parent with genotype B|B.

In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.

B|B X O|O

Alleles B B

O B|O B|O

100% of the offspring would be of blood type B.

Scenario 2: Parent with genotype B|O.

In this case, 50% of the offspring will have blood type O and 50% B.

B|O X O|O

Alleles B O

O B|O O|O

In no scenario would offspring of blood type A be possible.
