Why do deciduous trees lose their leaves?a. Deciduous trees lose their leaves to prevent oxygen loss.
b. Deciduous trees lose their leaves to defend from predators.
c. Deciduous trees lose their leaves to prevent nutrient and water loss.
d. Deciduous trees die in winter.

Answers

Answer 1
Answer: The answer is c. Deciduous trees lose their leaves to prevent nutrient and water loss.

Losing leaves is a trees' strategy to survive cold winters. It is known that trees primarily lose water through leaves. In the winter, there is no enough water to replace that lost water. If the trees were not to throw away their leaves, they will soon dry out. Also, before falling the leaves begin, reabsorb all nutrients from the leaves and store it for the cold winter. Thus, losing leaves is important to prevent both nutrient and water loss during the winter.

Ralph's wants to breed two of his prize bulldogs. For the dominant alleles, he has selected small ears (E) and a curly tail (T). Linus, the male bullbog, is homozygous dominant for both traits. Lucy, the female, is heterozygous dominant for both traits. A. What are Linus's and Lucy's genotypes?
B. What percent of their pups will have small ears and curly tails?
C. What percent will have large ears (e) and straight tails (t)?

Answers

Answer:

a) Linus's  genotypes - EETT

Lucy's genotypes- EeTt

b) 100 percent of their pups will have small ears and curly tails

c) 0 percent of their pups will have large ears (e) and straight tails (t)
Okay, so we have one homozygous, the prefix "homo" means "same" and we know that the male's genotype is dominate, so with the prefix "same" or "homo" we know the male's genotype must be EE, and TT. We also know that the female's genotype is heterozygous, and knowing that "hetero" means opposite, we know that she has the two opposite types of genes Ee and Tt

If animal cells contained chlorophyll, how would animal life be different?

Answers

Well there would no longer need plants to make air or take Carbon Dioxide, and the Carbon Dioxide would me our main meal
Chlorophyl is what allows plants to undergo photosynthesis, so animals would have a different way of producing food and energy for themselves (through photosynthesis). This would affect their necessity to hunt prey, eat vegetation, and/or other survival needs that are obligatory without chlorophyl. There are a lot of different answers, but a lot of them just rely on creativity and thinking outside of the box.

In the Cambrian period of Paleozoic era of geological time period, most of the modern animals appear. Chordates were the first animal phylum that appeared during this time period along with several indistinct animal species such as Archaeocyatha, brachiopods, trilobite, pirapulid, sponges etc. The prokaryotes, protists, fungi and algae that appered during this era continues to modification and development till today

Imagine that you work at the medical examiner's office for a major metropolitan city. As Chief Medical officer, you investigate suspicious deaths and provide toxicology services for the county. Unfortunately, it's been a busy week. In the past five days, seven people have died, all with similar symptoms. It is your job to examine the data and determine the cause of death for these victims. The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning, the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital, where she was pronounced dead. That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack. Sadly, the victim's brother and fiancée also collapsed later that night while the family gathered to morn his passing. Both had taken Tylenol to help them cope with their loss shortly before collapsing; neither survived.In the next four days, four other similar deaths were reported, all in the same neighborhood and all with similar symptoms. Are these seven deaths related? What is causing these people to die? It is your job to answer these questions before more deaths are reported.Symptoms exhibited by most patients: (i)-Dizziness(ii)-Confusion(iii)-Headache(iv)-Shortness of breath/rapid breathing(v)-Vomiting(vi)-Most deaths were very rapid, occurring within a few hours of symptoms.Explain whether or not you think these 7 deaths are related, and what questions you would ask the families of the victims.
