What causes objects to be or appear in different colors?
The colour of any any object is due to the wavelength of light it reflects or emitts, for example - sea appears blue because it absorbs the light rays of other wavelength but reflects back the blue one.

Explain how a single fertilized egg can develop into a multicellular organism.
Answer:
The fertilized egg goes through mitosis to create many identical copies of the original cell then those cells will differentiate into specialized cells of different tissues.
Explanation:
Compared to the endocrine system, the nervous system has afaster response, but the signal does not last as long.slower response, and a signal that does not last as long.faster response with a longer-lasting signal.slower response with a longer-lasting signal.
Answer:
Has a faster response, but the signal does not last as long.
Explanation:
The nervous system uses action potentials to transmit signals. Action potentials have a short duration and travel fast through neurons to inform in a fast way about different stimuli and allow rapid answers. On the other hand, the endocrine system uses chemical molecules to transmit their signals. As they travel through blood or together with other molecules, their signal is not transmitted as fast as in the nervous system. However, when they reach their destination and interact with the proper molecules, they start a series of changes that have a lasting effect in contrast with the nervous system.

A. matches both DNA strands
B. is a matching complement to part of one strand of DNA
C. is double stranded
D. is identical to the DNA strand it copied
B) Is a matching complement to part of one strand of DNA.

At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the ______________ layers and a second runs through the _____________ layers.
At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the parvocellular layers and a second runs through the magnocellular layers.
What are parvocellular and magnocellular layers?Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus.
Moreover, magnocellular cells make up the magnocellular layers of the lateral geniculate nucleus. They are relatively large cells that display specialization in detecting aspects of movement, such as the location, speed, and direction of a moving object.
Therefore, magnocellular (M) and parvocellular (P) neuronal pathways that originate in the retina and project to separate M- and P-dedicated layers of the lateral geniculate nucleus (LGN) situated in the thalamus.

Velocity of rolling ball = 1.97 m/s (Approx.)
Explanation:
Given:
Distance travel by rolling ball = 7.3 meter
Time taken by rolling ball = 3.7 seconds
Find:
Velocity of rolling ball
Computation:
Velocity = Distance / Time
Velocity of rolling ball = Distance travel by rolling ball / Time taken by rolling ball

Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

What is Petrified fossils?Petrified fossils are formed when minerals replace all or some part of once-living matter.
Petrified fossils result from a process known as permineralization which occurs when ground water solutions containing iron, carbonates, silicates or other minerals seeps through the remains of buried organisms (plants or animals).
When the water evaporates, the minerals remain and replace the organic matter to form a petrified fossil. This method preserves the most detail of an organism because it greatly retains the appearance of organisms.
Thus, option "4" is correct. .Compare the composition of the rock sample with other rock samples of known age.

Imagine you are sitting in a very quiet room when suddenly behind you there’s a very loud bang, like a firecracker exploding.
a. Predict how you would behave in response to the stimulus of the loud noise
b. What body systems would be involved in your response?
c. What would each of the body systems you described in 3b do?
Answer:
A. I would be startled by the sudden noise and would probably take cover some wheres. B. My nerves in my ears would send a signal to my brain causing my twitching muscle fibers to react quickly and heart might stop for a moment. C. The heart rate would increase the brain would be aware that there may be more sudden noises or events your adrenaline would be pumping and your quick twitch muscle fibers would probably be tense or contracted ready to make quick sudden movements if necessary and your hairs would stick up i guess as extra senses for if something would touch you.
Explanation:
not to mention but by the time you are startled your senses would probably be heightened due to you being aware of your surroundings such as you would be constantly looking around you would hear better and probably move quicker for a short period of time due to pumping adrenaline.

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Bb, Ee, and Hh that determine if gremlins have biting teeth (B), are evil (E), and have hair (H). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes: 48 bb ee Hh 36 Bb ee hh 400 Bb ee Hh 4 Bb Ee Hh 426 bb Ee hh 46 Bb Ee hh 38 bb Ee Hh 2 bb ee hh What is the recombination frequency between genes E and B
Answer:
The recombination frequency between genes E and B is 0.1 = 10%
Explanation:
Available data:
Cross: BbEeHh x bbeehh
F1) 1000 individuals in total
48 bb ee Hh 36 Bb ee hh 400 Bb ee Hh 4 Bb Ee Hh 426 bb Ee hh 46 Bb Ee hh 38 bb Ee Hh 2 bb ee hhTo know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.
Parentals:
400 Bb ee Hh 426 bb Ee hhDouble recombinants:
4 Bb Ee Hh2 bb ee hhSimple recombinant
48 bb ee Hh 36 Bb ee hh 46 Bb Ee hh 38 bb Ee HhComparing the parental and the double recombinant we will realize that they only change in the position of the alleles E/e. This suggests that the position of the gene E is in the middle of the other two genes, B and H, because in a double recombinant only the central gene changes position in the chromatid.
B------E------H
Now we will call Region I to the area between B and E and Region II to the area between E and H.
Once established the order of the genes we can calculate distances between them, and we will do it from the central gene to the genes on each side. First We will calculate the recombination frequencies, and we will do it by region. We will call P1 to the recombination frequency between B and E genes, and P2 to the recombination frequency between E and H.
P1 = (R + DR) / N
P2 = (R + DR)/ N
Where: R is the number of recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals. To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
So:
• P1 = (R + DR) / N = 48 + 46 + 4 + 2 / 1000 = 100/1000 = 0.1
• P2 = (R + DR)/ N = 36 + 38 + 4 + 2 / 1000 = 80/1000= 0.08
Now, to calculate the recombination frequency between the two extreme genes, B and H, we can just perform addition or a sum:
P1 + P2 = Pt
0.1 + 0.08 = Pt
0.18 = Pt
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU). The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
• P1 = 0.1 x 100 = 10%
• P2 = 0.08 x 100 = 8%
• Pt = 0.18 x 100 = 18 %
