Answer: Placenta
Explanation:
Placenta is the outer protective envelope around the developing embryo. It is attached with the lining of the uterus. It has a permeable membrane which allows the entry of oxygen and nutrients to be supplied to the embryo. It helps in getting rid of harmful substances like carbon dioxide and waste from the developing fetus body.

Can a female calico get pregnant?
No, calico cats can't breed, so they can't have children.
The calico cat is one of the most beautiful creatures in the world. Characterized by its unique fur, it is loved not only by cat lovers, but also by non-cat lovers.
Calico cats cannot actually breed due to their unique genetic makeup (and the fact that male calico cats are born sterile). The XXY configuration can lead to Klinefelter's Syndrome, a health problem we'll discuss later. These cats are too sterile and cannot be used to lineage other calico cats. Calico cats are believed to bring good luck and wealth to homes and families. It's also considered a little magical because it's three colors.

Teo proteins are formed from the same amino acids but have different functions suggest two factors which make from these proteins different
Answer:
Different sequence of amino acid and sequence of DNA.
Explanation:
All proteins are made of same amino acids but differ in their function because of different sequence of amino acids. The presence of different sequence is dictated by the nucleotide sequence of their genes. This different sequence of amino acid and sequence of DNA are the factors that are responsible for the different function of different proteins so we can conclude that sequence of amino acid and sequence of DNA are responsible for difference in function of proteins.

Every deliberate action you make, such as pedaling a bike, walking, scratching, or smelling a flower, involves neurons in the __________ nervous system.\
Every deliberate action you make, such as pedaling a bike, walking, scratching, or smelling a flower, involves neurons in the Somatic nervous system..
So , The correct option is B
The somatic nervous system is one of the peripheral nervous system's divisions. Only the skeletal muscles get motor signals from the central nervous system via the somatic nervous system.
The reactions that are consciously controlled are generated by the skeletal muscles. As a result, the somatic nervous system governs the body's voluntary motions.
Voluntary motions of skeletal muscles, such as walking, sniffing a flower, cycling, and so on, are therefore governed by neurons of somatic division.

What role does fossil fuels play in the carbon cycle? *
They are a sink of carbon. The carbon in fossil fuels hasn't been in the carbon cycle in
millions of years.
They absorb carbon dioxide from the atmosphere with their buffering ability
The fossil fuels are getting more acidic because they are absorbing too much carbon
dioxide
Fossil fuels are not involved in the carbon cycle. They are involved in nutrient cycling.
Answer:
A
Explanation:
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels.

What are 3 ways a mutation can occur in the DNA?
The three ways a mutation can occur in the DNA are, (1). Insertion
(2). Deletion (3). Translocation.
1. Insertion: The DNA strand receives more DNA nucleotides.
2. Deletion: The DNA sequence is altered as a result of the deletion of DNA nucleotides.
3. Translocation: The exchange of chromosomal segments.
Point mutations, or defects introduced in a single spot on a DNA molecule, include substitutions, insertions, and deletions. Sometimes errors can be significantly larger. Errors that relocate entire regions of a DNA molecule are known as chromosomal mutations, also known as gross or gene-level mutations. When cells divide and make duplicates of themselves, changes to the DNA sequence are called gene or genetic mutations. The human body is programmed with instructions from the DNA.

c. If you start skating down this hill, your potential energy will be converted to kinetic energy. At the
bottom of the hill, your kinetic energy will be equal to your potential energy at the top. What will be
your speed at the bottom of the hill?
We know that energy has to do with the ability to do work. Now we ought to know that the energy that is contained in an object that is just at a fixed position can be said to be potential energy while the energy that is in an object that is in motion is said to have the kinetic energy.
We know that both the kinetic energy and the potential energy or both the forms of mechanical energy and that the potential energy would be converted to kinetic energy as the object is falling down to the bottom.
a) The weight of the object is;
Weight = mass * acceleration due to gravity
Weight = 60 Kg * 10 m/s^2
= 600 N

ECT or electroconvulsive therapy is the treatment which is given for the treatment of depression, mental depression, suicidal patients, and others. In bilateral process one electrode is applied on the left and other on the right side of the brain. This way both hemispheres get the electrical treatment. Hippocampus and amygdala are two parts of the brain which are targeted in this process. These parts control the memory and emotion.
A zygote is the same as a gamete, they are both haploid cells *
True
False
Answer:
False
Explanation:
The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.
Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

Notice the two possible arrangements of chromo-somes in late prophase I. Considering what you know about DNA replication and meiosis, is either arrangement equally likely during the formation of tetrads in late prophase I
Yes, both arrangements of chromosomes in late prophase I are equally likely during the formation of tetrads. This is because, during meiosis, the homologous chromosomes replicate and then line up in pairs, known as tetrads.
During this process, the chromosomes can line up in any order, as long as the homologous chromosomes are paired together. Since the two arrangements of chromosomes in late prophase I consist of homologous chromosomes, they are both equally likely during the formation of tetrads.
Furthermore, during meiosis, the homologous chromosomes randomly separate and move to opposite sides of the cell in anaphase I, so the order of the chromosomes in late prophase I will not affect the outcome of meiosis.

What mutation did Lucy have?
Due to Lucy's high levels of deoxyadenosine in her blood, I was able to discover she had ADA-SCID. Her proteins were produced improperly and were shorter due to the stop codon mutation.
Since the gene mutation has no impact on the active site, there is no issue. Lucy's seizures were found to be caused by a mutation in the STXBP1 gene, which also causes the rare neurological disorder STXBP1 encephalopathy, following the completion of a genetic test known as an epilepsy panel.
I believe that the tRNA error is what is causing Lucy's ADA enzyme to malfunction. Lucy's 1500 base pair length is in line with the chart's usual range for gene length. However, Lucy only has half of that at 283.
