b.internal fertilization

Sexual reproduction provides genetic variation because the sperm and egg that are produced contain different combinations of genes than the parent organism. Sexual reproduction involves meiosis which is the process of a cell doubling its DNA, shuffling its genes and then dividing the shuffled DNA among four cells.Each resulting cell, or gamete from meiosis has only half the amount of DNA as the parent cell. So in order to form a new organism, two gametes, sperm and egg, must fuse, further mixing the genes to produce more genetic variation.

Which group would be found on the lowest branch of a phylogenetic tree of all life?

nikklg [1K]

I think the correct answer would be the second option. The group of archaebacteria would be found on the lowest branch of a phylogenetic tree of all life. Phylogenic trees are illustrations of a hypothetical evolution of the organisms and its relationship with the other organisms. From the listed options, the archaebacteria is most likely to be the most basic and simplest life form. It should be placed before the other options so at the lowest branch. This illustration is being used by scientists to describe how evolution and the connection of the organisms came about. It sometimes called as the tree of life.

A biology class is studying the effect of temperature on the amount of growth of duckweed in an aquarium. What type of data will

iragen [17]

Answer:

$\boxed {\boxed {\sf They \ will \ gather \ quantitative \ data \ using \ a \ thermometer \ and \ a \ balance}}$

Explanation:

First, let's identify the tools needed.

Since the biology class is studying the temperature, they will likely need a thermometer. Also, they are gathering information about the growth of the plants. This could use a balance of a meterstick.

Next, recall the difference between quantitative and qualitative data.

Quantitative: Measurable and numerical results found using scientific instruments/devices
Qualitative: Data found using the senses, such as descriptions and diagrams.

Since the class is measuring temperature and growth using tools, it must be quantitative data.

We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.
