Answer:
muscles
ribs
lungs
bronchioles
alveoli
diffuses
leaves
exchange
Explanation:
Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.
Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

FACURE IS 1CM ON A SIDE, CALCULATE ITS VOLUME. HINT WRITE OUT
Answers
Answer:
Surface area of the cube = 6cm²
Volume of the cube = 1cm³
Explanation:
The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:
S.A = 6 × a²
That is; a² + a² + a² + a² + a² + a²
Where;
a = length of a side of a cube
a² = area of one side of a cube
Note that, a cube has 6 faces
According to this question, a cube has a length of 1cm on each side.
Hence, S.A = 6 × 1²
S.A = 6 × 1
S.A = 6cm²
Volume of the cube can be calculated using the formula: a³
Where a = 1
Volume = 1 × 1 × 1
Volume = 1cm³

Which of the following best describes the genetic complement in each
daughter cell at the conclusion of meiosis?
A. A haploid set of chromosomes that are a recombination of the
parents' chromosomes
B. A diploid set of chromosomes that are identical to the parents'
chromosomes
C. A diploid set of chromosomes identical to the other daughter cells'
chromosomes
D. A haploid set of chromosomes that are identical to the parents'
chromosomes
Answers
Answer:
A
Explanation:
Meiosis end in four daughter cells that are haploid and contain half the chromosomes as the parent cell and genetically different from the parent cell and from each other, so A would be the right answer.
A haploid set of chromosomes that are a recombination of the parents' chromosomes best describes the genetic complement in each daughter cell at the conclusion of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Moreover, meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

which phase do chromatids divide and cell contents begin to be divided?
Answers
Answer:
anaphase stage
Explanation:
All of the chromatids are split in sync as the cell enters the anaphase stage. It is to be mentioned that the genetic material from prophase was called the chromatids not chromosomes (if you haven’t noticed it by now). However, since the sister chromatids are split in anaphase the genetic material is once again referred to as chromosomes.
1 Invasive plant species affect the interactions of living and nonliving components
of an ecosystem, so the removal of invasive plants is often necessary. The goal of
most plant-control methods is to disrupt or inhibit the function of different plant

reduce a plant's ability to absorb water.

Answer: Sensory Neurone and a synapse
[tex]\Huge\text{1) Sensory Neurons}\\\\\Huge\text{2) Synapse}[/tex]
_____________________________________[tex]\Huge\textbf{Reflex Action:}[/tex]Reflex action is a involuntary and instantaneous action in response to a stimulus acting over a reflex arc. Some reflex actions are inherited and innate while other are acquired through learning processes. These reflex actions are performed without the will of the animal & generally involve minimum number of neurons.
Reflex Arc:Many neurons work in group called reflex arc, There must be atleast two neurons in a reflex arc. A reflex arc is made possibly a shortest pathway so the body acts on an impulse before it reaches the brain, and usually it is coordinated by spinal cord and brain-stem.
The parts of reflex arc is given as,
A receptor, a sense organ in the skin muscle or other organ.An afferent or sensory neuron, which carries impulses towards the central nervous system.The central nervous system, where a synaptic connections are made between the sensory neuron and the inter-neurons.The efferent or motor neurons which makes a synaptic connection with the inter neuron and carries impulses out from the central nervous system.The effector, by which the animal responds to the environmental changes.The change in the body is detected by receptors which gives the information to the brain or spinal cord which is the control center via the sensory neuron. The control center decides the appropriate response and sends it to the effector via motor neuron which plays its role.
_____________________________________[tex]\Large\textbf{Synapse:}[/tex]
a synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells or the muscle.

a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answers
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.What are the Amino acids of the mutated DNA sequence: TAC ATC TTG GCG ACG ACT
Answers
Answer:
Tyr Ile Leu Ala Thr Thr
Explanation:
In a DNA sequence, a pair of three bases form a codon that codes one particular amino acid in the protein. Proteins are consist of 20 amino acids and these amino acids are coded by a pair of three bases.
There are four bases in a DNA - Thymine (T), Adenine(A), Guanine(G) and Cytosine(C).
The given mutated DNA sequence will also code for some amino acid, that is as follows:
TAC - Tyr (Tyrosine)
ATC - Ile (Isoleucine)
TTG - Leu (Leucine)
GCG - Ala (Alanine)
ACG - Thr (Threonine)
ACT - Thr (Threonine)
Thus, The mutated DNA sequence TAC ATC TTG GCG ACG ACT codes for Tyr Ile Leu Ala Thr Thr.
