The hormone relaxin, produced by the placenta and ovaries, functions to relax and soften various tissues in the body, particularly those involved in pregnancy and childbirth.
Relaxin is a hormone primarily produced by the placenta during pregnancy and the ovaries in non-pregnant females. Its main function is to relax and soften tissues in the body. During pregnancy, relaxin helps prepare the body for childbirth by promoting the relaxation of ligaments and joints, particularly those in the pelvic region. This allows for increased flexibility and expansion of the pelvic area, facilitating the passage of the baby during delivery.
Relaxin also affects other tissues and organs in the body. It relaxes smooth muscles, such as those found in the uterus, blood vessels, and gastrointestinal tract, contributing to increased blood flow placenta and reduced uterine contractions. Additionally, relaxin may have a role in breast development and lactation.
Overall, the function of relaxin is to prepare the body for pregnancy and childbirth by promoting tissue relaxation and flexibility, facilitating the processes associated with reproduction.

A 154-lb adult man performs a moderate level of physical activity and regularly consumes 2700 Calories a day. State whether the weight of the man will most likely decrease, increase, or remain the same. Use information from the data table to explain your answer.
The weight of the man will...
Explanation...
Answer:
Increases.
Explanation:
A 154-lb adult man regularly consumes 2700 Calories a day and performs a moderate level of physical activity, the weight of that individual increases because a 154-lb adult man needs only 2450 Calories a day and that person consumes 2700 Calories a day which is higher than their needs so these extra calories stored in their body and as a result the weight of that person increases.

Why do cells continue to divide in adult organisms?
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.

Describe at least two ways in which nitrogen is important to biological processes. (Hint: Find the biological chemicals that contain nitrogen.)
Answer:
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food. Nitrogen is a key element in the nucleic acids DNA and RNA, which are the most important of all biological molecules and crucial for all living things. Without amino acids, plants cannot make the special proteins that the plant cells need to grow. Without enough nitrogen, plant growth is affected negatively.

how does cell division help in growth and development of somatic cells and in gamete formation?
════════ ∘◦❁◦∘ ════════
[tex] \mathbb{CELL\:DIVISION\:(MITOSIS)} [/tex]
════════════════════
Well, im not sure what somatic cell is. But, the reason why cell division help in growth and development is because the main goal of cell division is to make more cells right? This is also why we keep growing (like taller/bigger) because more cells in our body because of that cell division.
#see pic of how cells in our body divide during mitosis
#sorry i borrow this ans for my latex experiment :v
════════════════════
Mitosis occurs in somatic cells this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.

Answer: Loops: 65%, whorls: 30%, and arches: 5%
Explanation:
The loops are 65% in the population, 30% are whorls and arches are 5%. The fingerprints are the patterns which include the friction ridge characteristics also called minutiae characteristics. These can be found in the soles of feet and palms of hand. At the distal end of finger the typical friction ridge pattern forms patterns like loops, whorls, arches, and composites which are patterns including two or more patterns. The loops are most common in the population the ridges emerge and end on the same side in this pattern. The loops are radial or ulnar loops depending upon the side in which pattern ends of the side of the bone thumb in case of radial and little finger in case of ulnar loop.

in which Domain & Kingdom would scientists classify an organism, whose cells contain a nucleus, has cell walls made of chitin, and does not have chloroplasts?
Answer:
The correct answer is -
Domain: eukarya
kingdom: fungi
Explanation:
A cell with a nucleus and cell wall made up of the chitin and does not have chloroplast, are all the characteristic features of an organism of kingdom fungi which is a group of eukaryotic organisms.
The cells with the nucleus are grouped in the domain eukarya while the prokaryotic organism does not carry a nucleus in their cell and divided into Archaea and bacteria. The chitinous cell wall without any chloroplast in the cell is one of determining features of the fungi kingdom.

Question 1/7 The Nile River carries sediments to the ocean. Over time, the sediments are compressed as more sediments are deposited on top of them. Which type of rock will be formed?
Answer:
Sedimentary Rock
Explanation:
Sedimentary rocks are formed from pieces of sediments or other existing organic matter or rock.
The sedimentary rock formation process begins with weathering which involves the breakdown of the sediments into small fragments. The next process is erosion, where water like the Nile River carries them to other places - in this case, the Ocean.
Over time, the sediments settle and become compressed as more sediments are deposited on top of them.
This leads to the formation of Sedimentary Rocks.
