Answer: Plants use photosynthesis to convert light energy from the sun to a more usable form during a process called energy transformation. Humans use energy transformations as well. The body takes the energy stored in food and converts it to a form that the body can use. This process is called cellular respiration.

Suppose a couple has come to see you to discuss the probability of their children having cystic fibrosis (CF). CF is known to be

m_a_m_a [10]

Answer:

The children that the couple may have a 25% chance of having cystic fibrosis and 75% chance of being carriers for the CF gene

Explanation:

We know that both parents are in the same situation. Let's start for example with the mother. She has one parent and one sibling with cystic fibrosis (CF). So, supposing that the allele of the gene that causes the disease is "f", as the disease is autosomal recessive, both, the parent and the sibling have the genotype ff.

Also, knowing that the other parent has a normal phenotype, but the sibling has CF, we deduce that the other parent of the mother must have a Ff.

So, despite the mother's phenotype is normal, her genotype is Ff (see the Punnett square 1) Couple's parents in the attached image). In other words, she is a carrier for the CF gene.

As the parents' situation is analogous, we can deduce that the father also has a genotype Ff and is also a carrier for the CF gene.

Now, if we look at the Punnett square for them (see the square 2) Couple in the attached image), we see that all their children will always have at least one copy of the CF allele, f.

More specifically, their children have 25% chance of having cystic fibrosis and 75% chance of having a normal phenotype but being carriers of the CF gene.

The original name for Asian Homo erectus was Group of answer choices Homo rudolfensis. Australopithecus. Paranthropus. Pithecant

Effectus [21]

Answer: Pithecanthropus erectus.

Explanation:

Between 1891 and 1892 Eugène Dubois believed he had found the "missing link", hypothesized by Ernst Haeckel, when he discovered some loose teeth, a skull cap and a femur - very similar to that of modern man - in the excavations he was carrying out in Trinil, located on the island of Java, Indonesia. Homo erectus erectus was the first specimen of Homo erectus to be discovered. Dubois first named it Anthropopithecus erectus and then renamed it Pithecanthropus erectus. The name Homo erectus means in Latin "erect man", wich means, "standing man", whereas Pithecantropus erectus means "standing ape-man".

So, Dubois published these findings as Pithecanthropus erectus in 1894, more popularly known as "Java Man" or "Trinil Man". In the 1930s the German palaeontologist Ralpf von Koenigswald obtained new fossils, both from Trinil and from new locations such as Sangiran and in 1938 von Koenigswald identified a magnificent Sangiran skull as "Pithecanthropus". It was not until 1940 that Mayr attributed all these remains to the genus Homo (Homo erectus erectus).
