Answer:

Female cones contain eggs and produce seeds.

Explanation:

Strobiles, also known as cones, are structures commonly confused with flowers, but should not be so named. Found mainly in gymnosperms, strobiles are responsible for the formation of gametes.

Female cones are larger and more complex than male cones. They have egg scales, spiraling around the strobile axis, and these cones produce seeds. At the time of reproduction, the scales of this cone are well separated, ensuring that pollen grains reach the eggs, germinate and produce the pollen tube, which is responsible for bringing the male gamete to the female. It is these strobiles that will house the seed after fertilization.

Why is it important to have MET at the beginning of mRNA?

astra-53 [7]

The Beginning of mRNA Is Not Translated
Interestingly, not all regions of an mRNA molecule correspond to particular amino acids. In particular, there is an area near the 5' end of the molecule that is known as the untranslated region (UTR) or leader sequence. This portion of mRNA is located between the first nucleotide that is transcribed and the start codon (AUG) of the coding region, and it does not affect the sequence of amino acids in a protein (Figure 3).

So, what is the purpose of the UTR? It turns out that the leader sequence is important because it contains a ribosome-binding site. In bacteria, this site is known as the Shine-Dalgarno box (AGGAGG), after scientists John Shine and Lynn Dalgarno, who first characterized it. A similar site in vertebrates was characterized by Marilyn Kozak and is thus known as the Kozak box. In bacterial mRNA, the 5' UTR is normally short; in human mRNA, the median length of the 5' UTR is about 170 nucleotides. If the leader is long, it may contain regulatory sequences, including binding sites for proteins, that can affect the stability of the mRNA or the efficiency of its translation.

Which group is more likely to survive significant environmental change, one like black-footed ferrets with almost no variation o

Shkiper50 [21]

Mountain lions with lots of variation because variation is important for species’ survival. If there is an environmental change that negatively affects organisms with a certain trait, variation can insure that the entire species will not be wiped out because some organisms within that species might not have that trait and can survive.

People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called:

motikmotik

People who use complex tools like plows, irrigation, and fertilizers to grow domesticated plants are called farmers, it is a large scale activity and it´s use to obtain food from the earth, we also have horticulture, does not require hundreds or thousands of acres of land, horticulture is also important, but is more limited to the domestic and individual context, and finally it is much cheaper because it is not done at large scales like the Agriculture.

Nina [5.8K]

Answer:

C, a long absolute refractory period.

Explanation:

Tetanus is not possible in cardiac muscle tissue because cardiac cells have longer action potentials and a very long refractory period compared to other cells. This helps prevent the heart from cramping and seizing up.

2. Wings of bats and birds serve the same function and are analogous structure.

3. Comparative anatomy is the study of the similarities and differences in structures in similar species.

4. Fossils demonstrate that during the evolution of the whale, the whale moved from land to the sea.

5. The human tailbone and appendix are vestigial organs.

6. The homologous structures are structures that are similar in related organisms because they were inherited from the common ancestor.

7. Comparative embryology is the study of similarities and differences in the embryo of different species.

8. The forelimb of all the mammals has basic bone structure.

9. Scientists who find and study fossils are called paleontologists.
