2 answers:

"All vertebrates are chordates", but not all chordates are vertebrates because a vertebrate just a type chordate. Not all chordates develop between vertebrates but all vertebrates develop on chordates.

Hope this helps :)

Answer:

B) All vertebrates are chordates.

Explanation:

Chordates (Filo Chordata) are all animals that have the notochord, in which they may be permanent or at some point in their life. Every vertebrate is a chord, but not every chord is a vertebrate. As an example of this phrase, we can cite the Protocordates represented by two subphyls: Urochordata (represented by the Ascidians) and Cephalochordata (represented by the amphioxes).

Thus, the inferior protorcordados or chordates are animals that have the notochord, but that do not have the bony skeleton, therefore they are not vertebrates.

Covalent Bonds

Explanation:

Covalent bonds are also called molecular bonds, and its defined as chemical bonds that involves the sharing of electron pairs between atoms.
Examples of compounds that contain only covalent bonds are methane (CH4), carbon (iv) oxide (C $O_{2}$ ), etc.

What is the estimated expected (mean) time for project completion?

il63 [147K]

The estimated expected (mean) time for project completion is 50 weeks, time management includes all the activities necessary to achieve the target date of delivery of the project. It includes the following activities: identification of activities, logical sequencing of activities, estimation of duration of activities, and preparation of the project schedule. For the preparation of the schedule we will see various methods such as resource leveling, simulation, and the critical chain method.

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

What is an inducable enzyme

Sonbull [250]

Answer:

An adaptive enzyme or inducible enzyme is an enzyme that is expressed only under conditions in which it is clear of adaptive value, as opposed to a constitutive enzyme which is produced all the time. The Inducible enzyme is used for the breaking-down of things in the cell.
