Indicate whether each statement is true or false. 1. Intramembranous ossification is completed by birth. (Click to select) 2. Within the spongy bone that is formed by intramembranous ossification, there are spaces that contain developing red bone marrow. (Click to select) 3. The end products of intramembranous bone formation are bones with outer compact bone surfaces and spongy centers. (Click to select)
Answer:
1. False
2. True
3. True
Explanation:
Intramembranous ossification is a process by which flat bones are formed. This mechanism involves the development of the bones on the top of the skull. Intramembranous bones are developed by the differentiation of the mesenchyme cells into osteogenic cells which in turn become osteoblasts. Intramembranous ossification formation is completed by the end of the adolescent growth spurt. The spongy bone is a highly porous structure localized inside the bones which is lighter than compact bone, while bone marrow is a soft connective tissue localized within the spongy portions of bones.
how can to plant cells from the same plant have different structures and functions
Answer:
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Any group of organic compounds consisting of carbon,
hydrogen, and oxygen
(5 Points)
carbohydrates & lipids
carbohydrates & proteins
proteins & nucleic acids
nucleic acids & lipids
Answer:
The most correct option is carbohydrates & lipids
Explanation:
Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen [for example starch, (C₆H₁₀O₅)ₙ] while lipids generally contains carbon, hydrogen and oxygen [for example fatty acid, CH₃(CH₂)ₙCOOH] but could also contain other elements like sulphur and phosphorus.
Proteins are made up of building blocks called amino acids. Amino acids are made up of an amino group which consist of nitrogen and hydrogen. Hence, proteins have a large number of nitrogen atoms thus not part of the answer.
Nucleic acids are composed of nitrogenous bases and phosphate groups and are also not part of the answer for this reason.
Which condition is autosomal recessive?
a) neurofibromatosis type 1
b) hemophilia
c) sickle cell anemia
d) Rett syndrome
Answer:
c, sickle cell anemia
Explanation:
When you are conceived you (generally) receive one set of chromosomes from your mom and one from your dad. Recessive diseases mean that you must receive 2 copies of the mutated gene (disease gene) to express the disease (one from mom and one from dad). Dominant means that you only need one copy of the mutated gene to express the disease.
Sickle cell anemia is a disease caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. The mutation is on an autosome (not a sex chromosome). You need two copies of the bad gene in order to express it.

What problem does this model of DNA solve
Answer:
c
Explanation:
Which can be accomplished by an interrupted mating experiment between Hfr and F- bacteria? Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome. Interrupted mating experiments can determine the physical distance between genes on the F- bacterial chromosome. Interrupted mating experiments can determine the genome size of the Hfr bacteria. Interrupted mating experiments can determine the DNA sequence of the Hfr bacterial chromosome. Interrupted mating experiments can determine the gene order on the F- bacterial chromosome.
Answer:
Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.
Explanation:
Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.
In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.

Which best describes when the body is working on counteracting an effect? when hormone levels in the body are all equal during a negative feedback loop during a positive feedback loop when the hypothalamus is signaling the pituitary gland
Answer:
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.

is liquid water more dense than ice
Answer:
Yes, liquid water is more dense than ice.
Explanation:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Paleontologists discovered fish fossils in the arid deserts of western Egypt. What does the fossil evidence most likely indicate about this area's geologic past? A: The desert was once a vast ocean. B: A giant ocean wave carrying sea life crashed onto the desert.
C: Mountains in the region once provided water from snowmelt.
D: The area was moved from the ocean to the deserts by plate tectonics.
Answer:
The correct answer is option A: "The desert was once a vast ocean".
Explanation:
One of the most prominent fish fossils that were found in the arid deserts of western Egypt belong to the Giant Catfish named Qarmoutus hitanensis, that lived roughly 37 million years ago as it was scientifically determined. The presence of this and other related fossils indicate that the desert was once a vast ocean. Actually, the arid landscape of this zone has been named Wadi Al-Hitan (which means Valley of the Whales) in honor to its past.
Distinguish between anabolism and catabolism?
Explanation:
Anabolism creates molecules the body needs for functionality and it uses energy in the process. Catabolism, on the other hand, breaks down complex molecules and releases energy which is available for the body to use.
