breathing involves the movement of diaphragm and Rib cage
true or false
Answer:
TrueExplanation:
It's a true statement as,
When we inhale the diaphragm moves downwards and the rib cage moves upwards and outwards to let enter the outside air containing oxygen come in.While we exhale the diaphragm comes to its position and the rib cage move downwards and inwards to let out the inside carbon-dioxide and other games out.Hence, we can conclude that breathing involves the movement of diaphragm and Rib cage.
Yes,very true! This is very true because out lungs are around our rib cage,and our lungs is where we breath. For example,right now take a breath in.....Hold.... and out. And one more time. Your lungs are moving in your rib has you do that!
Hope this explains better :)

why might a person observing a conifer have difficulty identifying the gametophyte state
Answer:
Conifers produce seeds, they do not rely on water to unite the sperm and the egg.
Explanation:
Cells and the organisms they make up reproduce through cell division. Some
organisms reproduce through mitosis, while others reproduce through meiosis and
fertilization. What advantage does meiosis give to organisms that reproduce sexually?
a
Meiosis ensures that offspring inherit genes from their parents.
b
Meiosis ensures that offspring will not inherit any genetic disorders.
c
Meiosis ensures that offspring are genetically different from their parents.
d
Meiosis ensures that offspring will have identical phenotypes to their parents.
The advantage meiosis give to organisms that reproduce sexually is meiosis ensures that offspring are genetically different from their parents.
What do you mean by meiosis?In sexually reproducing organisms, meiosis is a unique type of cell division that results in the production of gametes, such as sperm or egg cells.
Meiosis is a kind of cell division in physically repeating life forms that diminishes the quantity of chromosomes in gametes (the sex cells, or egg and sperm).
Gametes, or sex cells, are the end result of meiosis. Each of the four haploid daughter cells produced during meiosis has half the number of chromosomes as the parent cell.

Faris and his wife have normal skin color, but they both have a parent with albinism if
you know that albinism is a recessive trait. What is the probability that their first child
will have albinism?
Explanation:
If a man who's a carrier for albinism marries an albino what percentage of their children will be albinos, however if both parents carry the gene, there's a 1 in 4 chance that their child will have albinism and a 1 in 2 chance that their child will be a carrier. Carriers do not have albinism but can pass on the gene.

Suggest why the temperature of baby food must be controlled when the enzymes are added
Answer:
temperature plays an important role in biology as a way to regulate reactions.
Enzyme activity increases as temperature increases, and in turn increases the rate of the reaction. This also means activity decreases at colder temperatures.
which activities of the body are controlled by the autonomic nervous system?
The autonomic nervous system controls internal body processes such as the following:
Blood pressure.
Heart and breathing rates.
Body temperature.
Digestion.
Metabolism (thus affecting body weight)
The balance of water. ...
The production of body fluids (saliva, sweat, and tears)

Explain how carbon moves from one Earth System sphere to another
Answer: Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

The images show two different types of Galapagos tortoises that scientists believe descended from the same species. The first type (left) are found on islands that have high vegetation and few grasses. The second type (right) are found on an island that has large amounts of grasses and low-lying shrubs. What explains the type of turtle found on the islands with high vegetation?
A.
The environment triggered a gene mutation in neck length in order to help the turtle survive.
B.
Mutations are random, so it is by chance that turtles with longer necks live on these islands.
C.
Turtles with genes for long necks had a better chance of surviving to reach reproductive age.

You had the reactants necessary for cellular respiration, so why did nothing happen?
The teacher provided enough sugar with oxygen, but nothing happened immediately because there was no enzyme in the surroundings that could catalyze the slow reaction and make carbon dioxide and water. Here the enzyme is absent.
What is glycolysis?Glycolysis is a process of breaking down glucose and is the first step of cellular respiration, where sufficient energy is produced in the presence of oxygen. To produce energy for the cell, glycolysis requires a large number of enzymes to be carried out quickly.
Following glycolysis, the end product enters the citric acid cycle and the electron transport chain, where oxygen carries the final electron and carbon dioxide and water are released with ATP (energy). As the reaction is slow, enzymes act as catalysts and complete the reaction in a short time, but if this process is taken in the absence of the enzyme, then it will take years and years to complete.
Hence, without the presence of enzymes, the glucose and oxygen did not make carbon dioxide and water.

Explanation: is correct
Muscles that move the wrist and hand originate on bone carpals. The correct option is d.
What are carpals?The carpal bones are wrist bones that connect the distal portions of the forearm's radial and ulnar bones to the bases of the five metacarpal bones of the hand. There are eight carpal bones that are divided into two rows: proximal and distal.
The wrist is made up of eight tiny bones (carpal bones) and two large bones in the forearm — the radius and ulna. Each finger has one hand bone (metacarpal) and three finger bones (phalanges), but each thumb has one metacarpal bone and two phalanges.
The carpals are eight bones present in the wrist of the hand. It helps in moving the wrist, and it also attaches the hand to the wrist.
