Answer:
Osmosis is a form of passive transport that involves the movement of water or other solvents through a semi-permeable membrane into an area of higher solute concentration.
For example:
Plant root hairs absorb water from the ground. The roots have a higher solute concentration than soil which is why water flows into the roots.

When an infant suckles at its mother's breast, milk moves through the breast structures in what order
When an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple
When an infant suckles, milk is secreted from lactocytes into the alveoli (acinus). The milk is then squeezed from the alveoli so it can drain into the lactiferous ducts, milk drains from lactiferous ducts into lactiferous sinuses, and discharge through the nipple pores.
Hence, when an infant suckles at its mother's breast, milk moves through the breast structures in the order
Acinus - lactiferous duct - lactiferous sinus - nipple

An organism that reproduces sexually has a diploid number of 30. How many
chromosomes will a gamete of this organism have?
Answer:
Gamete of organism has a haploid number of chromosomes.
2n = 30
n = 15
A diploid cell containing 30 chromosomes will result in 15 chromosomes in each of the 4 daughter cells after meiosis occurs.
After first nuclear and cellular division (Meiosis I), each daughter cell will only have 15 chromosomes as homologous chromosomes are broken apart at Anaphase I of meiosis I. Chromosomal number is halved. After the second nuclear and cellular division (Meiosis II), each daughter cell will also have 15 chromosomes. This time, instead of the chromosomal number being halved, their chromosomal contents are halved. Sister chromatids are separated at Anaphase II of Meiosis II, resulting in daughter chromosomes each.

1. How do fossils form?
Explanation:
There is a LOOOONG process for this so here it is;
First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains. Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain. Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock. While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals. This process can take thousands or even millions of years.

describe two ways that you could determine the volume of a pair of dice
Answer:
The volume of a pair of dice could be gotten by measuring the
sides and calculating it via length/width/height. A second manner
would be displacement, where the dice are placed in a liquid with a
known density, and the mass of the liquid displaced is used to
determine volume.

Sheena's B lymphocytes (B cells) produced antibodies to protect her about 3-5 days after she was exposed to a virus. What type of immunity do antibodies provide
There are two types of immunity: These are acquired immunity and innate immunity.
The type of immunity that these antibodies provide is the acquired immunity.
When an individual's immune system responds to a foreign substance or pathogen, or when a person acquires antibodies from another source, this sort of immunity called the acquired immunity develops. It is a type of immunity developed over time in response to invasion of pathogens.Learn more about acquired immunity: https://brainly.com/question/21480961
Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.
According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.
Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as
Volcanism The rock cycle The wind The rainfall Among other
Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.
This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.

What process is the "copying" portion of protein synthesis? What is being copied? Why does it have to be copied?
The process of protein synthesis is known as translation. During this process, the mRNA is being copied into an orderly sequence of amino acids to produce a polypeptide.
During gene transcription, a fragment of DNA called gene is used as a template to generate a complementary messenger RNA (mRNA) sequence.
Afterward, this mRNA will be used as a template to create a protein by a process called translation.
The linear order of triplets of nucleotides or codons in mRNA will be used to add ordered amino acids to the growing polypeptide chain (i.e., the protein).
