Select all that apply.Which of the following animals filter feeds?

dolphins
fish
baleen whales
clams
sponges

Answers

Answer 1
Answer: Animals that filter feeds are called filter feeder. These are a sub-group of feeding animals that eat by filtering the food from water. They use a specialized filtering system from their body to filter their food. Filter feeders are important in cleaning the water. Examples of these are baleen whales, clams, sponges and some fishes. Thus, all are animals which filter feeds except dolphins.

In the alternation of generations life cycle fertilization requires two

Answers

The answer is two generations.

In the alternation of generations, there is alteration between two generations - haploid gametophyte and diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. Therefore, gametophyte reproduces with gametes. The zygote grows into diploid sporophyte which produces haploid spores. Sporophyte reproduces with spores, and new gametophyte develops.

Independent variable?
Dependent variable?

Answers

Answer:

Independent is what youre testing so it should be eating vegetables and fruits. and Dependent is what your outcome should be the dependent variable depends on you IV (independent variables) so the DV should be whether you run faster or not.

Explanation:

In snapdragons, there is one allele that produces red flowers and another allele that produces white flowers. Neither allele is dominant and heterozygous individuals have pink flowers. A plant breeder decides to cross a red flowered snapdragon with a pink flowered snapdragon. What percentage of the offspring do you expect will have red flowers?

Answers

You do:
R R
R
r
Your offspring would be: RR, RR, Rr, Rr
So, about 50% of the offspring will have red flowers
Your answer is
50%

Final answer:

When you cross a red snapdragon (RR) and a pink snapdragon (Rr), you will expect 50% of the offspring to have red flowers

Explanation:

In snapdragons, red and white flower color exhibits incomplete dominance, where the red (R) and white (r) alleles neither of them is completely dominant or recessive. This results in the heterozygous condition (Rr) appearing as pink flowers. In this case, the red flowered snapdragon would have a RR genotype, while the pink one would have a Rr genotype.

If you cross the red (RR) and the pink (Rr) snapdragons, the possible genotypes of the offspring would be RR and Rr, corresponding to red and pink flowers. Half of the offspring are expected to be RR (red), and the other half Rr (pink). Therefore, 50% of the offspring are expected to have red flowers.
