Answer:
a) both processes first break down glucose into pyruvic acid
Explanation:
Cellular respiration is the process through which cells of living organisms derive their energy. Cellular respiration can be carried out with oxygen (aerobic) or without oxygen (anaerobic). The oxygen actually acts as a final electron acceptor in the last stage of aerobic respiration process (ETC).
Cellular respiration starts with GLYCOLYSIS, which is the process whereby glucose is broken down to pyruvic acid. Glycolysis occurs in the cytoplasm and does not require oxygen to occur. In a complete respiration, the step progresses into the Kreb's cycle and Oxidative phosphorylation, which occurs in the mitochondria.
Hence, GLYCOLYSIS (break down of glucose to pyruvic acid) is a common process to both aerobic and anaerobic.
The main 3 subatomic particles that makes up an atom are protons, neutrons, and electrons.
Protons and neutrons exists inside the nucleus of the atom, while electrons moves freely outside the nucleus.
Protons are positive in charge, each element has their own specific number of protons, it's just like their ID number for the element, they cannot be changed.
Neutrons are neutral, just like as it name says. Usually they have the same number as the protons in most elements, but not all cases. Sometimes an element may even have a few different forms, called Isotopes specifically, where they have different number of protons for each isotope.
And electrons, are negative in charge. They're a lot more lighter comparing to neutrons and protons, therefore sometimes we neglect their mass in calculating maths. In an atom, the number of electrons must be the same as the number of protons, or else, the atom would no longer be an atom, but an ion instead.
Answer:
Chromosome number variation: B. Down syndrome
Loss-of-function allele : D. PKU
Physiological trait
: E. Lactose metabolism
Discovery-based science
: A. Human Genome Project
Genetic cross: C. Model organism
Explanation:
Down syndrome is a condition in which there is an extra copy of the chromosome number 21. Hence, it is a chromosome number variation.
Physiological traits refers to any function of a body. Hence, it matches with lactose metabolism.
Human Genome Project was a project under which the whole genome of the humans were sequenced. Hence, it is a discovery based science.
A genetic cross is made between model organisms to test for the offsprings that would be produced from a cross. Hence, genetic cross and model organism math with each other.
Answer:
1. axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
Explanation:
The axial skeleton consists of the bones of the head and trunk of a vertebrate including skull, and rib cage.
Bone marrow produces red blood cells, which carry oxygen in the blood.
Osteoblasts can become osteocytes, which are the third type of bone cells.
Osteoporosis is a bone resorption disease in which bones rapidly deconstruct faster than new bone tissue grows, and decreases the mechanical strength of bones.
Ligaments connects one bone to other at joint such as medial collateral ligament (MCL) and anterior cruciate ligament (ACL) that joins knee.
Hence, the correct answer for the question is as follows:
1.axial
2. red
3. Osteoblasts
4. osteoporosis
5. Ligaments
