Answer:
Explanation:
some gases prevent the escape of heat from the earth.There will be an increase in the percentage of such gases would cause the average temperatures to increase world wide.This is known as greenhouse effect.Carbon dioxide is one of the green house gases.An increase in the carbon dioxide content in the atmosphere woul cause more heat to be retained by the atmosphere and lead to global warming.
Answer:
Photosynthesis
Explanation:
The diagram shows a picture of a plant cell. Plants produce most of their energy through photosynthesis. The arrows also show the major reactants and products of photosynthesis.
It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation

Answer:
Clam.
Explanation:
Arthrophoda is largest phylum of the non-chordata. They are the segmented animals with jointed appendages. Their body is covered by exoskeleton and contains spiracles and body surface for respiration.
Insect, spider, crab and scorpion all are included in the phylum arthropoda. Clam is a bivalve shell that is included in the phylum mollusc. The body of clam is covered with an outer shell and their shells are connected by the abductor muscle. Hence, they are involved in phylum arthropoda.
Thus, the correct answer is option (b).
I think that correct answers are:
<span>Some of them lose their leaves in winter. (i.e. <span><em>Larix</em></span>)</span>
<span>They include the tallest plants (i.e<em>.Sequoia)
</em>I don't think they are the oldest type of seed plants, since in the past the classes like progymnosperms and seed ferns existed prior to the gymnosperms. But question isn't absolutely clear to me and I can't be 100% sure.
All of the gymnosperms have seeds unless human grows some seedless variant.
Gymnosperms don't have flowers like angiosperms do, but some people think that cone is kind of flower.
Male cones produce pollen, not female.
Hope I helped :)
