According to the endosymbiotic theory, large prokaryotic cells may have
engulfed smaller prokaryotic cells over 1.5 billion years ago. If the smaller
cells survived, the larger cells may have eventually evolved into eukaryotic
cells.

cells?
A. Specialized cells in a single organism
B. Predator-prey
C. Parent-offspring
D. Parasite-host

Answer 1

Answer: b

Explanation:

Answer 2

Predator-prey is the kind of relationship the original prokaryotic cell have.

This theory explains the origin of eukaryotic cells from prokaryotic cells.Mitochondria and chloroplast are the leading example that support the theory.

What is endosymbiotic theory?It states that eukaryotes arose as a result of a fusion of archean cells with bacteria.The archean engulfed but do not eat an ancient, aerobic bacterial cell.

How many alleles does a person carry for a trait?

Answers

Answer:

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism.

Most traits are determined by more than two alleles. Multiple forms of the allele may exist, though only two will attach to the designated gene site during meiosis. Also, some traits are controlled by two or more gene sites. Both possibilities multiply the number of alleles involved.

Explanation:

hope this helps...

Answer:

Explanation:

Everyone carries 2 alleles in Mendelian genetics. The exception to this is in polygenetic genes such as height. Alleles can be dominant, which is represented by a capital letter, or recessive, which is lowercase. A person can either have two recessive (aa), two dominant (AA), or a mix (Aa).

The LD50 for arsenic in humans is 13mg/kg. Which of the following approaches should be used to
calculate the number of grams of arsenic it would take to reach the LD50 in a 140-pound person?

Answers

Answer:

Explanation:

ap classroom

It would take 0.827 g of arsenic to reach the LD50 in a 140-pound person.

The lethal dose 50 (LD50) for arsenic in humans is 13 mg/kg.

What is the LD50?

LD50 is the amount of a material, given all at once, which causes the death of 50% of a group of test animals.

To calculate the number of grams of As that it would take to reach the LD50 in a 140-lb person, we need to convert 140 lb to kg using the conversion factor 1 lb = 0.454 kg.

140 lb × 0.454 kg/1 lb = 63.6 kg

The LD50 of As is 13 mg of As per kg of body mass. The mass of As to reach the LD50 in a 63.6-kg is:

63.6 kg BM × (13 mg As/1 kg BM) × (1 g As/1000 mg As) = 0.827 g As

It would take 0.827 g of arsenic to reach the LD50 in a 140-pound person.

Answers

Answer:

A decrease in species abundance.

Explanation:

(this was correct- connections academy)

if predators are introduced to an ecosystem with no known predators there is a decrease in species abundance.

What is the role of predators in the ecosystem?

Predators are an important part of a balanced ecosystem. Predators remove vulnerable prey, such as the old, injured, sick, or very young, leaving more food for the survival and success of healthy prey animals.

Also, by controlling the size of prey populations, predators help slow down the spread of disease.

Thus, if predators are introduced to an ecosystem with no known predators there is a decrease in species abundance.
