Please Help!!!! Mass extinctions have occurred repeatedly during the course of Earth's history. One of these events occurred at the end of the Cretaceous Period, during which the dinosaurs became extinct. Mammals flourished after the dinosaurs were gone. This led to a variety of genetically diverse species. Why did the mammals suddenly start diverging into different species after the dinosaurs were gone? a. Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce. b. Once the dinosaurs were gone, the mammals started having larger numbers of offspring in each litter to fill the empty niches. c. The mammals chose to move into the vacant niches the dinosaurs had occupied and change their body shapes to suit these new environments. d. Mammals began mutating rapidly once the dinosaurs died out and were able to create new species based on the mutations.
Answer:
Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce
Explanation:
Most of the predators were gone and suddenly niches were available so almost all the offspring were likely to survive and reproduce.
What is the maximum likely to take place if predators are brought to an environment without acknowledged predators?With no predators to manipulate the populace and modify feeding behavior, the prey species quickly degrade and over-run their habitat. As food becomes scarce, the population turns unwell and malnourished, and could both flow or crash.
What takes place whilst a keystone species is removed from an ecosystem?Keystone species have low practical redundancy. which means if the species were to vanish from the environment, no other species might be capable of filling its ecological niche. The atmosphere could be pressured to considerably change, permitting new and possibly invasive species to populate the habitat.

A woman consumes 500 grams of carbohydrate, 30 grams of protein, and 75 grams of fat in one day. How many total kcalories has she taken in, and how many and what percentage of kcalories are from carbohydrate, protein, and fat?
A. Total kcalories:
B. Percentage of kcalories from carbohydrate:
C. Percentage of kcalories from protein:
D. Percentage of kcalories from fat:
Answer and Explanation:
The computation is shown below:
A. For Total k. calories
= (Number of grams in carbohydrates × 1 gm of carbohydrates) + (Number of grams in protein × 1 gm of proteins) + (number of grams in fat × 1 gm in fat)
= (500 × 4) + (30 × 4) + (75 × 9)
= 2000 + 120 + 675
= 2795 k. calories
b. As we know that
1 gm of carbohydrates = 4 k. calories
So, for 500 grams it would be
= 500 × 4
= 2000 k. calories
Now the percentage is
= Total grams in carbohydrates ÷ Total kcalories
= 2000 ÷ 2795
= 0.72
= 72%
C. As we know that
1 gm of proteins = 4 k. calories
So, for 40 grams, it would be
30 × 4 = 120 k. calories
Now the percentage is
= Total grams in protein ÷ Total kcalories
= 120 ÷ 2795
= 0.043
= 4.3%
D. As we know that
1 gm of fat = 9 k. calories
So for 75 grams, it would be
75 × 4 = 200 k. calories
So, the percentage is
= Total grams in fat ÷ Total kcalories
= 200 ÷ 2795
= 0.072
= 7.2%
Which explanation provides support for continental drift theory? O Dinosaurs lived on many continents. Coal fields match up across continents. Tropical plant fossils were found in warm areas. Similar rock types are found across continents.
Answer:
Similar rock types are found across continents
Explanation:
Can I have brainliest?
Similar composition of rocks are present across continents that support the theory of continental drift.
Similar rock types are found across continents is the evidence that support the continental drift theory because at the boundaries of two continent there must be similar type of rock present. Scientist Alfred Wegener presented Continental drift theory in the early 20th century.
Wegener noticed similarities between two continents when he pieced together maps of Africa and South America. He noticed that mountain ranges present on both continents line up to each other which means they are made of similar type of rock so we can conclude that similar types of rock are present across continents.

Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring

Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.
Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.
Thus, X-linked traits are passed from parents to offspring via the X chromosomes only. Since both males and females have X chromosomes, it means both genders can have X-linked traits.Y-linked traits are passed from parents to offspring via the Y chromosomes only. Since only males have Y-chromosomes, it means that only the male gender can have Y-linked traits.More on sex-linked traits can be found here: https://brainly.com/question/1381309

5000 Thailand natives were tested for their MN blood grouping. This allele has incomplete dominance and analysis indicated a phenotypic distribution of 600M, 4000MN, 400N. What is the frequency of the N allele?
Answer:
0.28
Explanation:
This allele has incomplete dominance and analysis indicated a phenotypic distribution of 600M, 4000MN, 400N.
Using p+q = 1
Where q is the frequency of the N allele-
400N/5000 = 0.08 is the genotypic frequency out of 5000 in total - q²
Thus the frequency of the allele N is √q² = √0.08 = 0.28
The frequency of the N allele is 0.48
What is incomplete dominance?Incomplete dominance occur when a progeny of a particular parents gives or have a phenotype that combines both parents gene.
This phenotype is intermediate of the two parents and often unique.
Total population of Thailand= 5000
Allele P= 600M
Allele pq= 4000MN
Allele Q= 400N
According to hardyweingberg principles,
P+Q= 1
p2+2pq+q2=1
Therefore, to calculate frequency of allele N in the population we have;
N for Q= 400/5000=0.08
N for pq= 4000/5000=0.8
since pq contain both allele q and p in equal proportion we have
N for pq= 0.5*0.8 = 0.4
Frequency of N in allele N and MN is
0.08+ 0.4 = 0.48.
Therefore, the frequency of the N allele is 0.48

Which is not something that occurs in translation? A codon and an anticodon pair. A peptide bond is created. A molecule of mRNA is formed. An amino acid is added to a polypeptide.
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.
The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.
Note: A molecule of mRNA is formed during transcription
Answer:
A molecule of mRNA is formed.
Explanation:
Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.
