Answer:
The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample. Radioactive isotopes break down in a predictable amount of time, enabling geologists to determine the age of a sample using equipment like this thermal ionization mass spectrometer
The expression of a trait is directly dependent on the
A) Arrangement of amino acids in the protein synthesized
B) Shape of the subunits in the DNA molecule
C) Number if chromosomes present in the nucleus
D) Sequence of bases coded for by the ribosome
Answer: B
Explanation:
The question wants to know what the expression is directly dependent on.
The sequence of genetic expression goes like this:
DNA -> RNA -> protein
If we want to know the root cause of expression, we must look at the DNA, not the RNA or protein, because DNA determines the RNA and protein expression.
The Shape of subunits in DNA -> Sequence of bases coded for by the ribosome with RNA -> Arrangement of amino acids in the protein synthesized.
Why not C: Number of chromosomes present isn't a factor, because most humans, barring those with a genetic disorder, have 23.
B. The expression of a trait is directly dependent on the "Shape of the subunits in the DNA molecule."
What do you mean by expression of a trait?"Expression of a trait is termed as phenotype and it is dependent on many factors. A particular trait may become recessive if it gets combined with a dominant trait."
What causes the expression of a trait?"Genes also interact in patterns such as partial dominance or co-dominance, the trait is expressed as a mix between two genes. Those are the possibilities for one gene. Most traits are influenced by many genes, there are many different ways for those genes to influence how the trait is expressed."
What is the expression of a trait dependent on?"Expression of X-linked traits depends on a number of factors including a dominant versus recessive allele, and the gender of the offspring. One can determine the likelihood of producing a child with a particular trait using a Punnett square."

A. It could hear well underwater.
B. It lacked hind limbs.
C. Its teeth resemble modern whale teeth.
D. It was slow.
2. How can scientists determine whether an extinct animal gave birth on land or underwater?
A. Location of the hind limbs of the fetus
B. Position of the nostrils
C. Position of the head of the fetus
D. Location of the fossils
3. Fossils of Basilosaurus resemble that of modern whales because–
A. there are similarities in both anatomy and size.
B. they both have the exact same fossil coloring.
C. they lived during the same time period.
D. there are similarities in where the fossils were found.
Answer:
B,C,A
Explanation:
The statement that is not true regarding Ambulocetus is it lacked hind limbs. The correct option is B.
What are Ambulocetus?This cetacean ancestor was semiaquatic. It spent most of its time in the water but reproduced on land. Thewissen worries Ambulocetus natans resembled modern crocodiles in appearance and hunting style, consuming marine fish and maybe ambushing animals that wandered too near the water's edge.
It could have observed prey above water even while submerged thanks to the high, sideways-facing eyes on its head that resemble hippos.
2. Scientists can determine whether an extinct animal gave birth on land or underwater by the position of the head of the fetus.
3. Fossils of Basilosaurus resemble that of modern whales because there are similarities in both anatomy and size.
Therefore, the correct option is B, C, and A.

A canyon is a type of landform formed over millions of years as flowing rivers wear away the land and carve out steep cliffs. A person standing at the bottom of a canyon would look up at the tall cliffs and think they were mountains because they are so high. Using this information, the landform at the bottom of a canyon is most like
Answer:
Has flat ground, and has a river flowing in the middle of it
Explanation:
The river in the middle created the canyon, and the flat land is the small/big space that wasn't used, and stayed flat
Propose an explanation as to why beta cells would have a greater concentration of rough endoplasmic reticulum and ribosomes than some other cell types.
Answer:
Endoplasmic reticulum (ER) and Golgi apparatus are subjected to mass spectrometry have uncovered over a thousand different proteins assigned to the ER and Golgi apparatus of rat liver. In turn, led to the uncovering of several hundred proteins of poorly understood function and, through hierarchical clustering, showed that proteins distributed in patterns suggestive of microdomains in cognate organelles.

Which feature contains genetic material and is present in a eukaryotic cell but not in a prokaryotic cell?
Answer:
In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes separated from the rest of the cell by a nuclear membrane (also called a nuclear envelope).

why is the skin Cancer rates in Australia so high?
Answer: There's a lot of sun all year round
Explanation:
Australia is close to the equator which means it is hotter as the sun is closer. The heat from the sun damages our skin and causes skin cancer. In Australia the rates would be high because people are exposed to the sun more.
