For which object would a geologist use carbon-14 dating to determine age?
O Animal bones
O Fossilized plants
O Sedimentary rocks
O Volcanic rock
Answer:
O Animal bones
Explanation:
In the upper atmosphere, Radioactive Carbon-14 is usually produced. In plants, it is incorporated by photosynthesis into organic molecules, later ingested by hetrotrophs.
It is used for the radiocarbon dating process of fossils and formations. Because of the unstable nature of the isotope used and the consistent rate of decay, radioactive isotope dating is an important way of detection in organic material. Here, this is a the measure of the time taken for half of the radioactive material to break down- this is called the half life for Carbon this is 5,730 years.
In animals, the Carbon-14 ingested is eventually incoporated into their bones. After they die, bones become dessicated, and the Carbon 14 is slowly broken down to become Nitrogen.

Extrusive rocks are also known as volcanic rocks. Igneous rocks are classified according to their texture and mineral or chemical content. The texture of the rock is determined by the rate of cooling. The slower the rock cools, the larger the crystals form.
The two features of igneous rocks are determined by their cooling rate are Crystal Size and Rock Texture. Thus, option D is correct.
What are rocks?Rocks has been known as volcanic rocks. Igneous rocks has been classified just according to their texture including the mineral or the chemical content. The texture of the rock has been determined by the rate of cooling. The slower the rock cools, or the larger the crystals form.
Bioclastic rocks are wholly or partially comprised of compacted plant or animal remains. Bioclastic rocks will often have fossils within them upon discovery. Most sedimentary rocks contain either quartz (siliciclastic rocks) or calcite (carbonate rocks).
Bioclastic sedimentary rocks are clastic sedimentary rocks, where the broken pieces making up all or part of the rock happen to be pieces of biological life forms- most typically, these are shelly fossil fragments. Most bioclastic sedimentary rocks are marine, mostly because very few land animals leave enough remains to survive being transported.

Identify one species that is native to your geographical region in the United States. Speculate on how that species might be affected if they were to live in a warmer and wetter climate and then cooler and dryer climate.
Answer:
I live in the central region of the state of Florida in the Southeastern United States. The climate here is humid subtropical, with a defined rainy season from May through October. This season also sees afternoon thunderstorms that drop heavy but brief summer rainfall.
Florida is home to the largest population of American alligators (Alligator mississippiensis). Alligators are usually found in freshwater. They can only tolerate salt water for brief periods, because they do not possess salt glands to process the salt.
Because of strict conservation measures, the alligator (Florida’s official state reptile) has recovered from its former endangered species status. It remains under threat for habitat destruction because of the construction of water-management systems and increased levels of mercury and dioxins in the water supply. In a warmer and wetter climate, the alligator would be expected to thrive unless habitat destruction continued in that climate. In a cooler and dryer climate, the alligator would suffer from lower temperatures and loss of freshwater habitat.

How do Newton's Laws apply to the way an object moves?
Answer:
Force equals mass times acceleration.
Acceleration is directly proportional to force and inversely proportional to mass. This means that if you get pushed, the harder you are pushed, the faster you'll move (accelerate). The bigger you are, the slower you'll move.

Answer:
C
Explanation:
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

An individual that is heterozygous for flower color and for height (PpTt) is test crossed. What is the phenotypic ratio of the offspring
Answer:
9:3:3:1
Explanation:
This type of crossing that involves two characters is referred to as dihybrid crossing. Generally, when there is a dihybrid crossing for heterozygous genes for both parents, the phenotypic ratio is usually 9:3:3:1 as shown in the figure in the attached document below.
Assuming the colour is White (P) and Black (p) and the
Height is Tall (T) and short (t)
The possible phenotypes will be in the ration
9 - White and Tall
3 - White and short
3 - Black and Tall
1 - Black and short
It should be noted that phenotypic ratio (phenotype) describes the outward appearance (what can be see physically) and not the genetic make-up. Thus, where there is a dominant character like P or T, the recessive characters are not considered to have been expressed.
During nitrogen fixation, nitrogen gas in the atmosphere is converted into a form that ____ can use. a plants b animals c humans d all of the above
Answer:
A. Plants
Explanation:
Nitrogen fixation is one of the processes involved in the NITROGEN CYCLE. It is the process whereby atmospheric nitrogen (N2) is converted into nitrogenous compounds such as ammonia, nitrates by certain nitrogen-fixing bacteria such as AZOTOBACTER.
The nitrogenous compounds which nitrogen fixation converts N2 into are in a form that PLANTS can use. Plants cannot utilize nitrogen gas, hence, the importance of this conversion into a form that plant can make use of.

8 What is the complimentary mRNA sequence to the DNA sequence A-T-T-G-C-A.
Answer:
T-A-A-C-G-T
Explanation:
mRNA → Polypeptide
In order to translate an mRNA sequence into a polypeptide chain, it is important to establish the correct reading frame
The mRNA transcript is organised into triplets of bases called codons, and as such three different reading frames exists
An open reading frame starts with AUG and will continue in triplets to a termination codon
A blocked reading frame may be frequently interrupted by termination codons
Once the start codon (AUG) has been located and reading frame established, the corresponding amino acid sequence can be deduced using the genetic code
Example: (mRNA) GUAUGCACGUGACUUUCCUCAUGAGCUGAU
Answer: (codons) GU AUG CAC GUG ACU UUC CUC AUG AGC UGA U
Which of the following is NOT a type of transportation used in plants?
Individual cells
O Root to stem
O Cell to cell
Transport of sap within the xylem and phloem
Answer:
Transport of sap within the xylem and phloem
Explanation:
After photosynthesis sugars move through the mesophyll via plasmodesmata; here, they reach phloem sieve tube elements in vascular bundles. From the STEs, they are actively transported against their concentration gradient to the phloem.
When the sugars enter the phloem, water moves across from the xylem tube into the phloem. This increases the water pressure inside the phloem, causing the sap to move towards sinks.
Thus translocation of sap only involves the phloem.
Why do you think Lavoissier exposed a mouse to the gas he collected from mercury?
Answer:
Thus, in a confined space, candles were extinguished and mice died. Priestley believed his “pure air” enhanced respiration and caused candles to burn longer because it was free of phlogiston. For this reason, he called the gas that he obtained from decomposing mercury calx dephlogisticated air.
