How does oxygen binding change the quaternary structure of hemoglobin?

Answers

Answer 1

Answer: Oxygen binding causes a change in the quaternary structure of hemoglobin where hemoglobin changes quaternary structure from the T (tense) state that has a low affinity of oxygen to the R (relaxed) state that has a higher affinity of oxygen.

Explanation...

Answers

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.

Answers

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.

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?​

Answers

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.

Describe at least two ways in which nitrogen is important to biological processes. (Hint: Find the biological chemicals that contain nitrogen.)

Answers

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?

Answers

════════ ∘◦❁◦∘ ════════

[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.

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?

Answers

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.
