Answer:
These lungs are primitive and are not as evolved as mammalian lungs. Adult amphibians are lacking or have a reduced diaphragm, so breathing through the lungs is forced. The other means of breathing for amphibians is diffusion across the skin. To aid this diffusion, amphibian skin must remain moist.
Two common respiratory organs of invertebrates are trachea and gills. Diffusion lungs, as contrasted with ventilation lungs of vertebrates, are confined to small animals, such as pulmonate snails and scorpions.
Explanation:
Amphibians utilize gills for breathing early in life, and develop primitive lungs in their adult life; additionally, they are able to breathe through their skin.

B. Inversion and dorsiflexion of the foot is achieved by contracting the _________muscle.
C. The _________ muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The___________ of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Answer:
A. The d. extensor retinacula are the broad ligamentous sheets that contain the tendons of the anterior compartment muscles.
B. Inversion and dorsiflexion of the foot is achieved by contracting the a. tibialis anterior muscle.
C. The b. extensor hallucis longus muscle has a skeletal attachment on the distal phalanx of the first digit.
D. The c. lateral condyle of the tibia is a skeletal attachment site of the tibialis anterior muscle.
Explanation:
The two extra options are the f. extensor digitorum longus and the e. medial epicondyle. The first one is a muscle in the anterior part of the legs that originates in the anterior lateral condyle of the tibia and the anterior part of the fibula. Its insertion is in the four phalanges of the 2, 3, 4, and 5 digits. The first digit has the insertion of the extensor hallucis longus. The extensor digitorum longus and the b. extensor hallucis longus has the same function, the extension of the toes, the extensor hallucis longus only extends the first digit, and the extensor digitorum longus extends the other four digits simultaneously.
The second extra option, the medial epicondyle, is in the femur. It is a prominence in the distal part of this bone. The tibial collateral ligament and the Magnus muscle insert in this part of the femur.

An organism has the following characteristics: cell wall, heterotrophic, unicellular, and prokaryote. What kingdom does
it belong in?
• Animalia
• Protista
• Plantae
•Eubacteria
Answer:
The correct answer is - Eubacteria.
Explanation:
Eubacteria is a kingdom that comes under prokaryotic organisms. These organisms have many characteristic features that are as follows:
Body Structure: Eubacteria are single-celled organisms with a cell wall outside of the cell to protect them.
Food: Eubacteria are both auto- and heterotrophic which means they can be either autotrophic, they use both chemical synthesis and photosynthesis.
Animals lack the cell wall, planate are autotrophic and protists are eukaryotic organisms so the correct answer is eubacteria.

In the population of plant K, each plant has only red flowers or only white flowers. A farmer collected the seeds from plant K with red flowers to grow new plants. Explain why the new plants will have only red flowers
Answer:
nose
Explanation:
nosenosenosenosenosenosenosenosenosenosenose
The new plants will have only red flowers because the trait for red flowers is determined by a dominant gene, and all the plants in population K have the same homozygous genotype for the flower color.
In genetics, the flower color trait in population K is determined by genes present in the plants' DNA. There are two alleles, or gene variants, for the flower color: one for red flowers (let's call it R) and one for white flowers (let's call it r). The gene for red flowers (R) is dominant, meaning that even if only one copy of the gene is present in an individual's genotype (heterozygous), it will produce the red flower phenotype. On the other hand, the gene for white flowers (r) is recessive, which means it will only produce the white flower phenotype if two copies are present in the genotype (homozygous recessive).
In population K, all the plants have only red flowers, indicating that they must have the genotype RR. Since all the plants are homozygous for the dominant red flower gene (RR), when they reproduce, they can only pass on the dominant allele R to their offspring. As a result, all the new plants that grow from the seeds collected from these plants will also have the genotype RR and, therefore, express the red flower phenotype.
Since there are no plants in population K with the genotype rr (homozygous recessive), which is necessary for white flowers, there is no chance of white-flowered plants appearing in the new generation. Thus, the new plants will have only red flowers due to the uniformity of the homozygous dominant genotype in the original population.

NAME all the steps of Respiration. What is Produced in Each Step? What are the
Reactants Used in each step? What is the Final Product?
Answer:
The stages of cellular respiration are - glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
The products at each step are -
Glycolysis - 2 ATP, 2 NADH, and 2 pyruvate molecules
pyruvate oxidation - acetyl CoA and NADH
Krebs cycle - carbon dioxide, NADH, FADH2, and ATP or GTP.
oxidative phosphorylation - H2O, ATP, NAD+, and FAD+.
Reactants are used at each step -
Glycolysis - glucose
pyruvate oxidation - Pyruvate and CoA
Krebs cycle - Pyruvate
oxidative phosphorylation - the electron donors such as NADH and FADH2
The end product of respiration:
carbon dioxide and water are final products
Given the following cross TtYyRr x TtyyRr (T = tall; t = short Y = yellow; y = green R = round; r = wrinkled), what proportion of offspring would be expected to be short plants with round, green seeds. Write your answer as a reduced fraction - e.g. 1/2 proportion is
Answer:
3/32 ttyyR-
Explanation:
Cross: Tall, Yellow, Rounded individuals with a tall, green, rounded individual
Parentals) TtYyRr x TtyyRr
Gametes) TYR, TyR, TYr, Tyr, tYR, tyR, tYr, tyr (Parent one)
TyR, TyR, Tyr, Tyr, tyR, tyR, tyr, tyr (Parent two)
We need to know what proportion of offspring is expected to be short plants with round, green seeds. So we need to identify the gametes for these traits. The genotypes are:
Shot → ttRound → RR or RrGreen → yy⇒ Parent one can provide gametes tyR and tyr
⇒ Parent two can provide gametes tyR and tyr
(1/8 tyR x 2/8 tyR) + (1/8 tyR x 2/8 tyr) + (1/8 tyr x 2/8 tyR) =
2/64 ttyyRR + 2/64 ttyyRr + 2/64 ttyyRr =
1/32 ttyyRR + 2/32 ttyyRr =
3/32 ttyyR-
The branch of science which deals with the gene and inheritance is called biology.
The correct answer is 3/32.
When a parent has 3 characters and crosses with other parents which have a 3 character is called a trihybrid cross.
In this question, the genotype of the parent is given as follows:-
Mother - TtYyRrFather - TtyyRrThe gametes formed by the parents is as follows:-
TYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of motherTYR, TYr, TyR, Tyr, tYR, tYr, tyR, tyr is gamete of father.According to the law of inheritance it stated that the each gamete can fused with any gamete to increase the chances of variation.
Hence, after the crossing the number of offspring will form is 32.
Therefore the offspring which has a short plant with a round green seed is 3/32.
Hence, the correct answer is 3/32.

In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele
Answer:
32%
Explanation:
Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.
Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.
and another normal allele is = p
Here Q = 0.2 so P will be 1- Q or 0.8
By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.
