The illustration shows bones in four animals. The bones labeled as A are known as
and offer evidence of a common ancestor.
penguin
А
bat
alligator
human
extinct structures
O sequential structures
analogous structures
homologous structures
Answer: Homologous structures.
Explanation: The bones labeled A have similar structural arrangement in all the organisms but perform different functions in each organism
The bones labeled as A are known as homologous structures. Therefore, option D is correct.
What are homologous organs?Homologous organs are those present in several creatures that share a common ancestor and fundamental structure but differ in the roles they perform. The man's forelimbs, a cat's forelimbs, a whale's flippers, and a bat's wings are all examples of homologous organs.
Homologies are characteristics shared by two or more species and derived from their common ancestor. For instance, our common ancestor who lived more than 300 Mya ago left us with both the human five-fingered hand and the lizard's five-toed foot.
The forelimbs of penguins, bats, alligators, and humans are examples of homologous organs. Therefore, option D is correct.

Explanation:
similarities between the vas deferens of a male reproductive system and fallopian tube of a female reproductive system are ?
Answer:
Vas deferens → Male reproductive system
Fallopian tube → Female reproductive system.
Explanation:
In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.
1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.
3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

What is the bite force of a lion, compared to a chihuahua. Your time started when you started reading this.
Answer:
Chihuahua bite force in pounds is 3,900 (psi) pounds per square inch. The bite force of a lion is around 600 PSI. To say that a Chihuahua can bite at more than 6 times the strength of a lion is absolutely ridiculous. At first I thought the opposite.
Answer:
A Chihuahua can bite 6 times PSI a lion can. A lion can bite roughly 650 PSI, the small dog's bite is around 3900.

The table below lists the characteristics of genetic material isolated from a bacterium, a plant cell, a virus, and ribosome. Which source is the virus?
A.) #2
B.) #1
C.) #4
D.) #3
Answer:
Option D, Sample 3 is the sample extracted from a virus
Explanation:
Uracil is less expensive as compared to thymine and hence it is found in RNA. Also, RNA virus has RNA or single stranded DNA. The RNA of virus has Uracil instead of thymine in its genetic material
Hence, option D is the correct answer.
Option A is incorrect because sample 2 has two strands while virus has only 1 strand
Option B is incorrect because sample 1 has a circular DNA while virus as linear genetic material
Option C is incorrect because sample 4 has 2 stands while virus has only 1 strand and it also has thymine instead of uracil
Based on the data provided, the source of the virus is #3.
What is the nature of the genetic material of a virus?The genetic material present in a virus can either be DNA or RNA.
The genetic material is single stranded.
For RNA viruses, uracil is found in place of thymine.
From the data provided, there is only one single-stranded genetic material and it has uracil in place of thymine.
