Ribosomes cell and protien
The connective tissues and the epithelial tissue differ in their structure in the way their cells are organized. The cell of the epithelial tissue are organized in a closed-packed pattern, while the cells of connective tissue are organized in spread out pattern. Moreover, the connective tissues has blood vessels, but the epithelial tissue does not.
The epithelial tissues serve the purpose of protection. Protective layering is formed by the epithelial tissues in the body. The connective tissue such as bone provides support to the body. The blood vessel connectivity helps in the transfer of the newly formed blood cells.
The appearance of a person is determined by the tissues and other components. The skeletal determines the basic structure of the person. The epithelial tissues give more specificity to the figure of a person. The fats helps in determining the shape of the eyes and cheeks.
The fat in the cheeks is supposed to help the new born infants to suckle and chew. Moreover, it provides padding to the temporalis muscle while chewing. The fat behind the eyes helps in preventing damage to the eyes which may be caused if they rub with the bones of the skull.
It will be hard to open and close one's mouth if the temporalis muscle of a person is damaged. This will make forming words properly difficult. The damage to orbicularis oculi will make the blinking extremely difficult. The facial expressions will be distorted in such cases. The damage to the orbicularis oris will make the movement of the mouth difficult, which will cause poor articulation.
Answer:
I believe "B"
Explanation:
In the Sun, the flows of hot plasma in the convection zone create the solar magnetic field. This is sustained by nuclear fusion in the Sun. ... The number of sunspots on the sun increase and decrease over time in a regular, approximately 11-year cycle, which is, in fact the solar magnetic activity cycle.
1.What is the probability that a sperm from the father will contain the PKU allele?
Probability = ½
2.What is the probability that an egg from the mother will contain the PKU allele?
Probability = ½
3.What is the probability that their next child will have PKU?
Probability = ¼ (because each parent has ½ chance ½ X ½ = ¼)
4.What is the probability that their next child will be heterozygous for the PKU gene?
Probability = ½ (because each parent has ½ chance of donating the ‘P’ allele and ½ chance of donating the ‘p’ allele (½ x ½) + (½ x ½) = ½
Answer: Tightly wound chromosomes, composed of DNA, must unwind before replication. Cell replication splits a cell into two parts, both of which become new, fully functioning cells. Before this can happen, however, cells require a full complement of DNA for each of the new daughter cells that will form as a result of the split. Because of this, DNA makes a copy of itself in a process known as replication during interphase, a stage that occurs before cells divide.
Cell Phases: Mitosis is the process by which parent cells each divide into two identical daughter cells. However, this majority of the cell's time is spent in interphase, during which it performs normal metabolic functions necessary for the organism, such as manufacturing protein. DNA occurs during the S phase of interphase, sandwiched between the G1 and G2 phases. The cell uses checkpoint signals to ensure at the end of G1 that it is big enough to replicate and at the end of G2 to determine whether or not DNA replication has succeeded. If so, the cell can undergo mitosis, at which point DNA winds up tightly for easy transport during the process.
DNA Replication: Replication begins with DNA unwinding and unzipping, its two strands coming apart. While only one side is the “correct” code, containing the actual genetic information used to build the organism’s proteins, both can be the base for a new strand of complete DNA. The enzyme DNA polymerase matches up each base with the correlating base: adenine with thymine and guanine with cytosine. When each pre-existing base has been matched to a nucleotide, which also contains the sugar and phosphate of the DNA’s backbone, the strand is complete.
