5 0

Answer: nucleolus

Explanation: Ribosomes are manufactured in the nucleolus. Ribosomes are the sites where protein synthesis takes place. Ribosomes are usually made up of two subunits: one large subunit and one small subunit. Ribosomes are manufactured and assembled in the nucleolus. Ribosomal proteins combines with four ribosomal RNA strands in the nucleolus to form two ribosomal subunits: one small subunit and one large subunit that make up the complete ribosome

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male
Fed [463]

Answer:

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

What is the importance of crossing-over?
nikklg [1K]

Answer:

b.It increases the likelihood that daughter cells contain different genetic material.

Explanation:

Morgan and Cattell for the first time used the term ‘crossing over’.  Crossing over takes place during prophase I of meiosis. During crossing over, chromosome segments of non-sister chromatids of homologous chromosomes get exchanged. As a result, the daughter cells acquire different genetic materials. Thus, it provides genetic variation by creating a new combination of genes or get recombination and produces hybrids.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to
Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒       =\sqrt{(3-(-2))^2+(4-4)^2}

⇒       =\sqrt{(3+2)^2+(0)^2}

⇒       =\sqrt{25}

⇒       =5 \ units

and,

⇒ ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒       =\sqrt{(3-3)^2+(-1-4)^2}

⇒       =\sqrt{0+(-5)^2}

⇒       =5 \ units

Now,

The total trail length will be:

= RS+ST

= 5+5

= 10 \ units
