Female cones produce what? Which contain eggs

Biology
2 answers:
Lyrx [107]3 years ago
8 0

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.

Reil [10]
They release CO2 (just like us, when we breathe). But, when plants are photosynthesizing. They release the oxygen through the same pores that allow the CO2 to enter their leaf cells.

If round pea shape is dominant to wrinkled pea shape, which of the following genotypes
Kobotan [32]

Answer:

C. rr

Explanation:

The dominant genotype will always be denoted by the capital version, or in this case R.

The round pea shape is dominant to the wrinkled pea shape, which means that, in the Punnett Square, the combinations of RR, Rr, rR, will all come out to be round pea shape.

The last box, rr, would be the one that gives the wrinkled phenotype.

In this case, by ratio, wrinkled phenotype show up 25%

                    by ratio, round phenotype show up 75%.

In a sample population of people, 36% have the recessive trait of "free" earlobes (q2). What is the frequency of the dominant al
ICE Princess25 [194]

Answer:

Explanation

Given that 36% are recessive in traits

100-36 = 64% for dominant traits considering a whole population to be 100%

P=dominant allele

q= recessive allele

P2= dominant genotype

q2= recessive genotype

according to hardyweinberg principle, p+q=1

64/100= 0.64 frequency for dominant traits or genotype, therefore

p2=0.64

then

P=√0.64

p= 0.8

Therefore, dominant allele frequency (p) for the population is 0.8

Describe what messages are sent by the nervous system when you go outside wearing a sweater on a very hot day.​
mr_godi [17]

Answer and Explanation:

In homeostatic control processes any deviation from the norm sets into motion the appropriate corrective mechanisms which restore the norm. This rectification occurs through negative feedback. When you go outside wearing a sweater on a hot day, the body sends messages to the CNS and the following occurs:

  • The superficial blood vessels vasodilate so that more blood flows near the surface. This encourages heat loss.
  • Sweating and panting. Sweat secreted by the sweat glands evaporate from the surface of the body as it absorbs latent heat.
  • The metabolic rate falls so that the body generates less heat. You also become less active
  • Behavioural response by seeking cooler areas, cold drinks or removal of the sweater.
