True or false: Torn cartilage heals slowly because it lacks a direct blood supply and nutrients have to be obtained by diffusion

Explanation:

That is a true fact the lack of blood flow creates a slow healing process

Answer: Cartilage is not innervated and therefore relies on diffusion to obtain nutrients. This causes it to heal very slowly. The main cell types in cartilage are chondrocytes, the ground substance is chondroitin sulfate, and the fibrous sheath is called perichondrium.

Which of the following is a covalent compound?
V125BC [204]

Answer:

Water is a covalent compound.

Explanation:

covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.

Example:

Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).

Properties:

1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.

2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

3. Covalent compounds have lower melting and boiling points.

What makes a tunicate more complicated than a sea sponge?
Umnica [9.8K]

Given what we know, we can confirm that in summary, what makes a tunicate more complicated than a sea sponge is cellular differentiation.

<h3>What is cellular differentiation?</h3>

This is what we call the cells ability to specialize itself into a specific cell type. Some examples of this in humans include:

  • Heart cells
  • Digestive cells
  • Reproductive cells
  • etc.

Due to this, tunicates have evolved different tissues, organs, and complete cell types, making them much more complicated organisms than sea sponges.

Therefore, we can confirm that due to the multiple tissues, organs, and systems developed through cellular differentiation, tunicates have become more complicated than sea sponges.

The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ
Verdich [7]

Answer:

The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.

Explanation:

<u>Available data</u>:

  • The gene for petal color in a flower has incomplete dominance
  • Two A1 alleles (A1A1) express black color
  • Two A2 alleles (A2A2) express white color
  • One of each allele (A1A2) express mottled color

In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:

Parental)    A1A1    x    A1A1

Gametes)  A1   A1       A1   A1

Punnet Square)     A1         A1

                   A1    A1A1     A1A1

                   A1     A1A1     A1A1

F1 Phenotypes: 100% black flowers

F1 Genotype: 100% A1A1

There are 0% of probabilities of getting a mottled offspring.
