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.

Heat creates energy... the atoms move faster and faster, which changes the state of matter.
for example:
if a solid is heated, it turns to a liquid
if a liquid is heated, it turns to a gas
hope this helps?

Answer: Variation allows some individuals within a population to adapt to the changing environment. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population.
Answer:
What the scientist is doing incorrectly is hitting a rock with a hammer without protective equipment and on the same table where containers with chemical or biological substances are found.
Explanation:
Biosafety is an important aspect of laboratory work. Conducting studies in rocks, trying to fracture them with the use of a hammer is an incorrect practice carried out by a scientist when he does not use protective equipment and has containers with substances on the same work table.
<h3>what could he do to make their work in the lab safer?</h3>
- <em>Wear gloves, protective apron and protective eyewear.</em>
- <em>Break the rock on a work table where there are no containers that could break by accident, spilling their contents.</em>
<h3>why is it important to follow these procedures?</h3>
It is important to follow these procedures because injuries to hands, body or eyes can be avoided by fracturing the rock. In addition, it prevents the breakage of containers with chemical or biological products, which could contaminate the work area or cause damage to the scientist.
