Which of the following statements is MOST accurate: Group of answer choices Animals evolved during the Cambrian Explosion because the Earth was organized into a supercontinent called Pangea Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant Animals evolved during the Cambrian Explosion because the Earth had just recovered from an asteroid impact Animals evolved during the Cambrian Explosion because carbon dioxide on Earth had become abundant
Answer:
Animals evolved during the Cambrian Explosion because oxygen on Earth had become abundant.
Explanation:
Photosynthesis could be responsible for the rise in the amount of oxygen in the seas and atmosphere near the beginning of the Cambrian. This rise of oxygen concentration allowing the evolution of larger animals having complex respiratory and circulatory systems. So we can conclude that evolution in the physical and genetical characteristics of animals occur during the Cambrian Explosion.

The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics. The key can be used to classify each of the four animals represented below. Which answer choice shows the correct classification group for each animal? 1. Wasp = group D; Ant = group D; Tiger = group A; Bird = group B 2. Wasp = group B; Ant = group A; Tiger = group D; Bird = group C 3. Wasp = group B; Ant = group D; Tiger = group A; Bird = group C 4. Wasp = group D; Ant = group A; Tiger = group A; Bird = group B
Complete question:
The dichotomous key below provides a way to classify some animals into groups according to their physical characteristics.
Dichotomous Key
I wings------------------go to II
no wings------------- group A
II feathers---------------group B
no feathers----------go to III
III two legs------------- group C
six legs---------------group D
The key can be used to classify each of the four animals represented below ⇒ wasp, ant, tiger, bird
Which row in the chart shows the correct classification group for each animal?
Row Wasp Ant Tiger Bird
(1) group D group D group A group B
(2) group B group A group D group C
(3) group B group D group A group C
(4) group D group A group A group B
Answer:
Row Wasp Ant Tiger Bird
(4) group D group A group A group B
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsExplanation:
When analyzing a dichotomous key, you just need to pay attention to the given descriptions and carefully observe the organisms you have.
The key describes specific morphological traits of each organism that are useful to differentiate it from other organisms. So all you need to do is to follow the instructions given in each step, and the key will guide you directly to the answer.
In the exposed example you have four organisms: wasp, ant, tiger, bird
The provided key gives you three steps: I, II, III.
Step I:
wings------------------go to II
no wings------------- group A
Here the key tells you to separate, from your group of organisms, the ones that have wings from the ones that do not have wings.
wasp and bird have wings → So you need to go to step IItiger and ant do not have wings → So they belong to Group AStep II:
feathers---------------group B
no feathers----------go to III
Now you only need to consider the bird and the wasp, which are the two organisms that have wings.
Here the key tells you to separate the one that has feathers from the one that does not have feathers.
Bird has feathers → So it belongs to the group BThe Wasp does not have feathers → So you need to go to step IIIStep III:
two legs------------- group C
six legs---------------group D
In this last step, the key takes you to two possible groups. But you only have one left organisms, which is the wasp. So what you need to do is to observe how many legs your wasp has. It is an insect, so it has six legs. The wasp belongs to Group D.
You do not have any organism that belongs to group C.
To sum up, according to the given information you could group the group of organisms as follows:
Group A: Tiger and Ant → They do not have wingsGroup B: Bird → It has wings and feathersGroup D: Wasp → It has wings, does not have feathers, and has six legsin your own words, write the definition for Phagocytosis.

Interphase happens before MITOSIS and MEIOSIS
A. True
B. False
Answer:
A. True
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

5. What is the difference between radial and ulnar loops?
1. Radial loops point toward the pinky (radius bone) and ulnar loops toward the thumb (ulna bone)
2. Radial loops point toward the thumb (radius bone) and ulnar loops toward the pinky (ulna bone)
3. Radial loops point right and ulnar loops point left
4. Radial loops point toward the head (radial region) and ulnar loops towards the feet (ulnar region)
Answer:
Radial Loop – This pattern is similar to the ulnar loop, but the difference is the turns point toward the thumb instead of the small finger.
The difference between radial and ulnar loops is that the radial loops point toward the thumb (radius bone) and the ulnar loops toward the pinky (ulna bone). Thus, the correct option for this question is B.
What is a Radial loop?A radial loop may be defined as the term that significantly describes the radius of a bone in the forearm that generally adjoins the hand on the same side with respect to the thumb.
While the ulnar loop governs the same arrangement of bones in the forearm but they usually adjoin the hand on the same side with respect to the pinky (small) finger.
Therefore, the radial loops point toward the thumb (radius bone), and the ulnar loops toward the pinky (ulna bone) is the statement that represents the difference between radial and ulnar loops.

If a cell has a diploid number of 8 (2n = 8) before meiosis, how many chromosomes will be in each of the four daughter cells after meiosis II if one pair of homologous chromosomes experiences nondisjunction in meiosis I? Show how you got the answer by drawing out the process, starting with the diploid cell undergoing meiosis I (where nondisjunction occurs) and then meiosis II to get the four daughter cells.
Answer:
The final product is four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.
Explanation:
If nondisjunction occurs during meiosis 1, a pair of homologous chromosomes fail to separate, and one of the daughter cells will have the two chromosomes while the other cell will not get any chromosome from the pair.
If meiosis 1 occurs normally, but nondisjunction occurs in meiosis 2, sister chromatids fail to separate.
The usual process of meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of chromosomes of the original one.
If the diploid number of the original cell is 8 (2n=8), then under normal conditions, each haploid daughter cell should have 4 chromosomes (n = 4).
But in the exposed example, one pair of homologous chromosomes experiences nondisjunction during meiosis I (in the attached file, you will recognize this pair as the red one). The other chromosomes separate as usual. So one of the daughter cells will have one extra chromosome than expected (five instead of four), and the other daughter cell will lack one chromosome (three instead of four). Meiosis II occurs normally. The final result is the formation of four gametes, two of them with 5 chromosomes, and the other two with 3 chromosomes each.

Muscle is coordinated systems of contractile tissue for better performance.
It can also be defined as an organ made of muscular tissue that moves in a specific way when it contracts.
A person's muscles enable them to move, speak, and chew.
They manage digestion, respiration, and heartbeat.

Hypertonic solution
A hypertonic solution is a particular type of solution that has a greater concentration of solutes on the outside of a cell when compared with the inside of a cell. Water crosses the cell membrane in both directions, but more water leaves the cell than enters it. Therefore, the cell will shrink due to exosmosis.
