Answer:
Horseshoe crabs are chelicerates, which means they're made of two segments, the cephalothorax and the abdomen. The cephalothorax is a fusion of the head (cephalon) and chest (thorax), and the tail is part of the abdomen. Trilobites, on the other hand, are composed of 3 parts, cephalon, thorax, and pygidium. In this body plan, the pygidium is the tail and is a separate segment of the body. Due to these differences, it seems that the two species are not closely related, however, it's quite possible that they share a yet-undiscovered common ancestor.

There are several factors that lead to genetic variation in organisms. Which of the following is NOT one of those factors?
A. Producing offspring that are genetically identical to the parents
B. The random combination of alleles from both parents
C. the process of crossing over during meiosis
B. the formation of sperm and egg cells during meiosis
Answer:
A
Explanation:
Genetic variation means difference in organisms. If they are identical, they are not different, and therefore there is no variation.
Producing offspring that are genetically identical to the parents is the factor that does not lead to genetic variations in organisms. So, it's A.
What do you mean by Genetic variations?Genetic variations may be defined as the existence of dissimilarities in sequences of genes between individual organisms of the same species.
Genetic variation may be induced by the random combination of alleles from both parents, the process of crossing over during meiosis, the formation of sperm and egg cells during meiosis, and many more ways.
Therefore, the correct option for this question is A.

Darwin's finches are often used to illustrate evolution. Evaluate the finch beaks shown in the picture. Choose ALL of the statements that correctly explain the evolution of finch beaks.
A) As the environment changed, the finches grew longer beaks to allow them to get food out of fruits.
B) Finches with longer beaks settled on the same island with smaller beaked birds. Over time, they bred, producing medium beaked birds that became more common in the population.
C) There are finches with different types of beaks in the population. During a drought, those with shorter beaks are not able to find sufficient food and die, leaving them unable to reproduce and pass the trait on to offspring.
D) A random mutation introduced the shorter, thicker beak into the population. However, those with thinner, longer beaks were better able to get nectar from the island's flowers. Those birds with the shorter, thicker beaks were unable to get enough food to survive.
E) A disease swept through the island killing many of the insects that were common on the island, leaving the birds who ate insects from the ground starving. The finches that had thicker beaks and could get food from tree bark were able to continue to survive and reproduce, increasing this trait in the population.

Are all deserts hot? Choose the best answer.
Question 5 options:
yes - temperature and plants/animals determine whether an area is a desert biome.
no - only the plants/animals determine whether an area is a desert biome.
yes - precipitation and temperature determine whether an area is a desert biome
no - temperature does not determine whether an area is a desert biome
Answer:
No - temperature does not determine whether an area is a desert biome
sorry if I am wrong :|
Explanation:
No, temperature does not determine whether an area is a desert biome which is why it's not always hot.
What is a Desert?
This is defined as a barren area of landscape which is characterized by little precipitation.
This area isn't best suited for plants and animals and the temperature varies and isn't hot all the time thereby making option D the most appropriate choice.

What started as a 7-year-old’s desire to do something about the palm oil crisis plaguing orangutan habitats has turned into a fully scalable nonprofit called Purses for Primates that has raised over $27,000, to protect orangutans and their shrinking habitat. Allison is also a Barron Prize winner, and collects gently-used handbags from across the U.S., resells them at fundraising events, and donates 100% of the proceeds to Orangutan Outreach, a New York City-based conservation group.
She is a founding member of the group’s extensive children’s program, Forest School 101, and serves as the program’s current ambassador. “Orangutans have such an intelligent mind. They teach each other and grow together,” she tells Teen Vogue. “I have and always will feel personally responsible to try my best to rally as many people as I can to help save these creatures.” She attributes much of her success, though, to her BFF, Natalie Katsikas, who stuck by her side over the past 11 years while other friends faded away or called her efforts “dorky.”
distinguish between multiple alleles and polygenic inheritance
Answer:
Multiple alleles are more than two alternative forms of a gene, located at the same loci of homologous chromosomes. In polygenic traits, several genes are involved in determining a single trait. Multiple alleles follow complete dominance or codominance while polygenic traits follow codominance or incomplete dominance.
