Dinosaurs left behind fossils of their bodies in the earth. What does this have to do with fossil fuels?

The fossil of an organism with a sprawling gait and middle ear bones, found in a 250-million-year-old rock layer.

historically, non-mammalian synapsids were believed to have advanced from reptiles, and consequently defined as mammal-like reptiles in classical systematics, and primitive synapsids were also known as pelycosaurs, or pelycosaur-grade synapsids.

Mammals belong to a larger institution of animals referred to as synapsids. these are vertebrate animals that produce amniotic eggs and have a single hole, or temportal fenestra, in the back of their eye socket. The sister organization to the synapsids are the sauropsids, all cutting-edge 'reptiles' (which includes birds) and their fossil family.

The fossil that provided the strongest evidence for the discovery of a transitional species between early non-mammalian synapsids and mammals is: the fossil of an organism having a sprawling gait and middle ear bones, that was found in a rock layer that was 250-million-year-old.

Synapsids were the earliest known reptiles that were present during the Carboniferous period. The term synapsid refers to the fused arch. They evolved from the basal amniotes along with the Sauropsids.

Gait refers to the way of movement of any animal. Various animals have different types of gait or locomotion. These can be crawling, flying, walking, creeping, slithering or swimming.

Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.

Explanation:

The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain.  The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.

The adenine would have been inserted after the 24th base in the mRNA sequence, corresponding to the sixth amino acid in the protein sequence, which is Leu.

DNA transcription is the process by which genetic information encoded in DNA is converted into RNA molecules. During transcription, the DNA double helix is unwound and one of the strands is used as a template for RNA synthesis. RNA polymerase, an enzyme, moves along the template strand, adding complementary RNA nucleotides to the growing RNA strand. The process continues until the RNA molecule is completed.

The process of transcription is tightly regulated to ensure that genes are expressed at the right time and in the right cells. Transcription factors, regulatory proteins that bind to specific DNA sequences, control the rate and specificity of transcription.

Mutations that disrupt transcription can lead to a variety of diseases, including cancer and genetic disorders.

The reason because replication is carried in the two strands of DNA, is due to in each of them, the RNA polymerase acts in differents ways; while in the 5' - 3' strand, it's replicated continuosly being the leading strand, in the 3' - 5' strand, it's replicated discontinuosly, beomg the lagged strand. This allows the cell to be more efficient in the production of the needed proteins, since these RNA fragments would eventually be used in the formation of aminoacids by the intervention of ribosomes.

The given RNA sequence is AUGUAACGAUGCGUCGUGGCAUCAUGCUGCGUCAGCGGCGAGUCUGACCCGUCUCUAACAGGACGGCCGGGCGUUGUCGUUGA.

We can use the codon chart to determine the amino acid sequence.

The codon chart is used to determine which amino acid is coded by a particular codon in a strand of DNA/RNA.A codon is a sequence of three nucleotides in DNA or RNA that encodes for a specific amino acid.

Each codon codes for a different amino acid.

For example, the codon AUG codes for the amino acid methionine.

To determine the amino acid sequence, we start reading the RNA strand from the start codon AUG and continue reading until we reach a stop codon (UGA, UAA, or UAG).

Then we write down the amino acid sequence for the codons we read, using the codon chart.

Here, the sequence starts with AUG, which codes for methionine.

After that, the next codon is UAA which is a stop codon, so we can stop.

The amino acid sequence is therefore Methionine. So, the answer would be Methionine (Met).

Answer:

- The co-worker is wrong, it is indeed possible

- Genetically engineered plants may represent a milestone to alleviate hunger in the world

Explanation:

During photosynthesis, plants use carbon dioxide (CO2) from the air and water (H2O) from soil and rain in order to produce oxygen and glucose, which is a sugar (molecular formula C6​H12​O6). Subsequently, plants release oxygen into the air and store energy (and carbon compounds) in the form of glucose. In consequence, an increase in the photosynthetic rate is directly associated with an increase in both the production of oxygen and glucose. On the other hand, genetically engineered plants can help to reduce hunger in developing countries. In consequence, it is acceptable to develop genetically modified plants as long as contemplating regulatory measures aimed at producing safe products (for example, by avoiding the introduction of genetically engineered genes into wild crop populations).

Stevens says that the intensity of a feeling is: decreased as the physical stimulus became more intense.

Option B is correct.

The force per unit charge that is applied to a positive test charge that is at rest at that location is represented by the electric field, which is described mathematically as a vector field that can be connected to any point in space. An electric field can be created by either the electric charge or time-varying magnetic fields.

The intensity (I) of a wave is determined by dividing the surface area over which the energy is dispersed by its rate of energy transfer. To put it another way, intensity refers to the rate of energy flow per unit area. The amount per unit region is estimated by force. Intensity is typically used to describe the size of waves per unit area. Another way to think about a wave's strength is its power per unit of area over time.

Therefore, Stevens asserts that the intensity of a sensation is as follows: diminished as the force of the actual improvement increments.

The change to the experimental design that would improve the reliability of the engineers' measurements is C. testing single samples from more than three locations.

From the information given, it was stated that the civil engineers wants to determine whether the porosity of surface soil affects aquifer recharge rates-the ability of aquifers to refill with water and they conduct the study to determine the porosity of the surface soil at various locations.

There are just three of the chosen locations. In order to obtain more accurate results than gathering soil samples from just three places, an area must have a wider variety of soil types with varied porosity.

Therefore, the correct option is C.

Complete question:

In many regions of the world, humans rely on underground water supplies called aquifers for fresh water. The amount of water an aquifer can store depends in part on the porosity of the rock or sediment in which the water is stored. Porosity is a measure of the amount of liquid that can be stored in a material and is related to the amount of empty space that exists between individual rock or sediment particles.

A group of civil engineers wants to determine whether the porosity of surface soil affects aquifer recharge rates-the ability of aquifers to refill with water. The engineers conduct the following study to determine the porosity of the surface soil at various locations. The results of the study will then be compared with the recharge rates of the aquifer each location supplies with water.

1. Collect one 200-milliliter (mL) sample of soil from each of three locations.

2. Place each soil sample in a beaker.

3. Add 200 mL of water to each sample and allow the water to saturate the soil.

4. Measure the amount of standing water in each beaker (amount of water the soil did not absorb).

5. Determine the amount of water in the soil sample by subtracting the amount of standing water from 200 mL.

6. Divide the amount of water in the soil sample by 200 mL and multiply by 100 to determine the percent porosity of the soil.

Which change to the experimental design would improve the reliability of the engineers' measurements?

A. using a liquid other than water to determine porosity

B. using flasks instead of beakers

C. testing single samples from more than three locations

D. testing more samples from each location
