Which manufactures ribosomes?
m_a_m_a [10]

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

You are enjoying a spring day but expect a storm to arrive soon. As the storm arrives and the rain begins to fall, you notice th
anastassius [24]

Answer:

c. Cold front

Explanation:

Cold fronts are bodies of air with cooler temperatures than the surrounding air. The general effect cold fronts have is that they cause a drastic change in the weather. This is because when they interact with the warmer air, they produce precipitation.

The storm most likely, came with an advancing mass of cold air, which caused the dramatic drop in temperature that was experienced. This is what is known as a cold front.

Embryonic development includes all of the following except
Thepotemich [5.8K]

The answer is (b.) fertilization

The fertilization is the stage where the egg cell or the so-called ovum fused with the sperm cell which eventually leads the development of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes mitotic divisions or also known cleavage process.

How does wound healing relates to cell division ( i need a paragraph pleasee)<br> HELP ASAP
klio [65]
The process of cell division whereby the chromosomes are duplicated and distributed equally to the daughter cells is called mitosis. The cells stretch out when you get a wound and explode, that is why you have blood but then when more cells are formed it gets tightly together and closes up the wound in which then separates to make more cells.

ASAP PLS There are lots of big words in genetics! One way to start thinking about the process of meiosis is to ask yourself some
mihalych1998 [28]

Answer:

1) the genes and chromosomes do not double after each generations because parental sex cells are haploid and only contain one set of chromosomes. During fertilization the two cells fuse to form a diploid zygote with two copies of genes and chromosomes. For example a normal human has 46 chromosomes (2 copies of 23 chromosomes) during reproduction gametes which contain 23 chromosomes (haploid) fuse to form an offspring with the correct number of chromosomes ( 23 + 23 = 46).

2) offspring only receive one set of chromosomes from each parent so to maintain the chromosome number of humans. If this did not happen you would not be the same species.
