Attracted by the sweet nectar that each flower offers, the bees crawl around on the petals to find the perfect sucking position. As they do so, their furry bodies are dusted with beads of pollen. As they fly from blossom to blossom in search of more of the sweet energy drink, they transfer pollen from the male part of the flower to the female part, and so fertilize it. Not long afterwards, the plant's ovaries swell into fruit, which by late August turn into precious, oval-shaped nuts.

Answer:

A couple of things that will happen if you change the number of protons, electrons, and neutrons in an atom. If you change the number of protons in an atom somehow, then there will be less positive charge. If you change the number of neutrons somehow, nothing will happen because it carry's no charge at all.

Which are true statements about how chemical energy can be stored and released through chemical reactions?

Answers

Answer: The question is incomplete as the options are not given but the options is gotten from another websites.

1 .As bike tires roll across the sidewalk, friction is created and they become warmer.

2. Solar energy from the sun is absorbed by solar panels, which transforms to chemical energy when it is used as electricity.

3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

5. Thermal energy causes energy stored in fireworks to convert to kinetic, light, and sound energy.

The correct options are 3 and 4.

3. As food is digested, molecule bonds are broken, allowing new molecules to form that can be used by our bodies.

4. Energy stored in organic fuels are used for heat and electricity/ When batteries are connected to a circuit, a reaction occurs inside the cell producing electrical energy.

Explanation:

Chemical energy is stored in food but when the food is broken down into smaller pieces or nutrients by the process of digestion, chemical energy are released which is use to drive different body functions or mechanisms.

Chemical energy are stored in circuits. When these circuits are connected to battery, the chemical energy are released and these energy are then converted to electrical energy to produce heat or light .

The earliest plants to appear on the earth, based on the fossil record, are _____. The first plants to grow on land were ______, which lack vascular tissue. _____ were the first group of land plants to evolve vascular tissue, allowing them to grow taller. The _____ group produces seeds that develop in cones, while the ______ group produces seeds that develop in fruit. Each of these groups of plants has a reproductive cycle that includes a ____ form that produces seeds or spores and a _____ form that produces sperm or eggs.

Answers

Answer: Cyanobacteria, bryophytes, Pteridophytes, Gymnosperms, Angiosperms, Sporophytic phase, and Gametophytic

Explanation:

Cyanobacteria or blue green algae were the first or earliest known plants which appeared on earth they performed the process of photosynthesis by using water and carbon dioxide in the atmosphere to produce oxygen gas. Bryophytes were the first land plants on earth including the mosses and liverworts, these plants did not had the vascular system and true roots, stems, and leaves.  Pteridophytes are the plants that have vascular system. Gymnosperms are the plants that have naked ovules and the seeds are enclosed in the woody covering called cone. The angiosperms are the flowering plants, which develops seeds after fertilization gets enclosed in a fruit. The sporophytic phase, involves the development of a dominant sporophyte which produces spores which on germination produces a gametophytes which produces gametes (male and female) for fertilization.

What are the genotypes of the parents shown in this pedigree if the disorder is a recessive disorder? What are the genotypes of the parents shown in this pedigree if the disorder is a recessive disorder?

both parents have the disorder

both parents are DD

both parents do not have the disorder

both parents are dd

Answers

Answer:

If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.

Explanation:

When a disorder or disease is recessive it requires two alleles with the disorder to manifest. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.

Parents

♂ Dd

♀ Dd

Both without disorder but presenting the altered gene, which makes them carriers.

Alleles      D      d

D             DD    Dd

d              Dd    dd

The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.

In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.

How much heat is needed to raise the temperature of 50.0g of water (4,182J/kgC) by 25.0C

Answers

Answer:

Q = 5227.5 J

Explanation:

Given data:

Mass of water = 50.0 g

Temperature increase by = ΔT = 25°C

Specific heat capacity of water = 4182 J/Kg.°C

Heat required = ?

Solution:

(50.0 g×1 Kg/1000 g=0.05 Kg)

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

Q = 0.05 Kg ×4182 J/Kg.°C ×  25°C

Q = 5227.5 J
