Answer:
1) in the direction of the applied force
2)when the movement is not in the direction of the applied force it is not work. But if a component, or part of the motion is in the direction of the applied force it is work.
3)Joules/sec
4)Force/displacement
6)Wedges and lever
5)conduction
6)radiation
7)there is no heat flow
8)The average kinetic motion of the particles increases, there is more thermal energy
9)The average kinetic motion of the particles decreases, there is less thermal energy
10)transverse wave
11) sound waves
12)they transfer energy through oscillations in matter
13)the speed of the pitched baseball
14)to detect speed and direction of blood flow
15)green and violet are reflected and red is absorbed
16)visible light
17)as heat
18)infrared light/infrared energy
19)reflection
20) yes, the forces emitted by having the same charge repells them.
21)the flow of electrons
22)You open the circuit and the electrons can't flow
23)You closed the circuit and the electrons can flow
24)I think you meant bipolar, this means 2 poles
Answer:
Meiosis I, a reductional division of two haploid cells produces offspring cells that are not genetically identical with the event of recombination. Haploid girl cells have half the original/parent cell chromosomes.
Explanation:
meiosis II, an equational or mitotic division, divides the haploid cells created in meiosis I to produce four identical daughter cells that ultimately form the male/female gametes (egg/sperm).
Here chromatids split in contrast to meiosis I when homologous chromosomes apart.
Yes I do we have about 71% of the world is water and from that water 96.5 is ocean water and about 4% is fresh water it is mostly found in Glaciers <span />
Answer:
The rock type, newspaper ,
cotton or plaster of Paris to collect the fossil
Method of collection .
Documentation or labelling.
Magnifying glasses.
Explanation:
Fossil is fragile as it contain the remains of dead of plants and animals on it. Fossil can be collected from sedimentary rocks instead of metamorphic rocks because sedimentary rocks contain strata or layers of fossils.
The method of collecting fossils entails how the fossil is collected and it should be wrapped in news paper, aluminum foil or plaster of Paris so as to preserve the imprints of the remains of dead plants and animals.
The collected fossils should be labelled properly and well documented to avoid missed up or loss of some certain information using pen or paints.
Magnifying glass can be used to view it.
Answer:
Probability of having a child with this genotype: CcFf is 
Explanation:
Given -
Curly hair (C) is dominant to straight hair (c)
and
Freckles (F) is dominant to not having freckles (f)
Genotype of man heterozygous for curly hair and no freckles is Ccff
Genotype of woman with straight hair and heterozygous condition for freckles is ccFf
The cross is between Ccff and ccFf
The following offspring would be produced
Ccff and ccFf
Cf Cf cf cf
cF CcFf CcFf ccFf ccFf
cF CcFf CcFf ccFf ccFf
cf Ccff Ccff ccff ccff
cf Ccff Ccff ccff ccff
Genotype –
CcFf – 4 in number
ccFf - 4 in number
Ccff - 4 in number
ccff - 4 in number
Phenotype
CcFf – heterozygous for both the curly hairs and freckles
ccFf – straight hairs with heterozygous freckle condition
Ccff – Heterozygous curly hair with no freckles
ccff – staright hairs with no freckels
probability of having a child with this genotype: CcFf is
