What are Metals, Nonmetals and Metalloids? 32 POINTS! i need to know this.

Answers

Answer 1
Answer:
Search the the periodic table for more info

Explanation:
Metals are, well, metals. Examples are Iron, Copper, and Aluminum.

Non Metals are simple; they are not metals

Metalloids are complex to define, so I will let the Oxford Dictionary explain for me;
an element whose properties are intermediate between those of metals and solid nonmetals or semiconductors.

why do blue whales explode when they die

Answers

Answer:

Gas build up inside the body.

Explanation:

When a blue whale dies, the body starts decomposing, and the gases cannot escape, resulting into the explosion.

Answer:

A decomposing whale carcass generates gases which build up inside their stomach and large internal organs. This then causes them to expand, but whale skin and blubber are tough so the gases become trapped inside. Whales can apparently hold in gasses, or the “death burp,” for long periods after they die, sometimes resulting in massive and extremely messy explosions.

2.)Hasani is a farmer. He uses a weed killer to control the weed population growth on his farm. Weed killers can stop the transportation of certain minerals in plants through the hair root tissue. Explain why.
How to answer this 2 question. Thanks ​

Answers

Answer:

1) sap is mostly sugar, so an aphid must consume a lot of sap to meet its nutritional requirement for protein.

Insects tend to be most active in the early morning that's why aphids are mostly found in the daytime

2) These herbicides interrupt cell division, which stops root growth in seedling weeds. Plants die because they cannot take up enough water and nutrients to sustain growth.

City water management is analyzing water samples from the local river for water pollutants that could be toxic to humans if found in drinking water. Their collection data is below.


Samples

Nitrates

Carbamates

1

Two miles downriver from drinking water uptake facility

12 mg/L

2

One mile downriver from drinking water uptake facility

9 mg/L

3

One mile upriver from drinking water uptake facility

8 mg/L

4

Two miles upriver from drinking water uptake facility

10 mg/L

0.05 mg/L

Toxic levels reached when nitrates are greater or equal to 10 mg/L and/or carbamates are greater or equal to 0.04 mg/L.

Which sample location(s)have nitrates or carbamates at toxic levels that could be collected by the water uptake facility?
Samples 1, 2, 4
Samples 1 and 4
Samples 3 and 4
Only sample 4

Answers

Aquatic toxicity is found in the four sample sites. But since the water uptake facility collects water from upriver, the correct option is C. Samples 3 and 4.

What is aquatic toxicity?

Aquatic toxicity is the property of a substance to causes harmful effects on aquatic or water-dependent organisms.

Aquatic toxicity can be either,

Sharp ⇒ nocive effects after a short exposition periodCronic ⇒ nocive effects after a long exposition period

Aquatic toxicity depends on the substance type and its concentration in water.

--

According to the problem statement, toxic levels are reached when

nitrates are greater or equal to 10 mg/L

and/or

carbamates are greater or equal to 0.04 mg/L.

Sample 1 ⇒ Two miles downriver from drinking water uptake facility

Nitrate → 12 mg/L ⇒ > 10 mg/L ⇒ toxic Carbamate → 0.06 mg/L ⇒ > 0.04 mg/L ⇒ toxic

Sample 2 ⇒ One mile downriver from drinking water uptake facility

Nitrate → 9 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 2 mg/L  ⇒ > 0.04 mg/L ⇒ toxic

Sample 3 ⇒ One mile upriver from drinking water uptake facility

Nitrate → 8 mg/L ⇒ < 10 mg/L ⇒ not toxic Carbamate → 0.04 mg/L ⇒ = 0.04 mg/L ⇒ toxic

Sample 4 ⇒ Two miles upriver from drinking water uptake facility

Nitrate → 10 mg/L ⇒ = 10 mg/L ⇒ toxicCarbamate → 0.05 mg/L ⇒ > 0.04 mg/L ⇒ toxic

The four sample sites have toxic levels. Both of the substances concentrations or at least one of them reaches the toxic level at each site.  

However, since water uptake facility can colect water from upriver, we only need to consider these sample sites.

The correct option is C. Samples 3 and 4.

. b. 50% Type A, 50% Type O
50% Type AB, 50% Type 0
d. 50% Type B, 50% Type O
c.

Answers

Answer:

A. 50% Type A, 50% Type B

Explanation:

To answer this we can draw a punnett square.

Since o if recessive, it can only be expressed if it is not masked by a dominant allele. Therefore the male with type O blood has the genotype oo. A and B are co-dominant, so the woman has genotype AB.

_ | A | B

o |Ao | Bo

o | Ao | Bo

Since A and B are dominant alleles, they will mask the o allele. Therefore genotype Ao will be a Type A phenotype, and genotype Bo will be a Type B phenotype.

Therefore, the phenotypic probabilities for this cross is 50% Type A, 50% Type B. Hence, the answer is A.

A air front is typically a transition zone between two unique temperature/humidity. Usually, one front would push the other away (typically if summer is hot, then the warm front will push away the cold, and for the winter, if it's cold, it's the opposite).

A stationary front, on the other hand, is when there is no change in the over all temperature for the region(s), and a occluded front is when the fronts mix, where it is followed by rain and a equillibrium of the temperature, whether to a warmer or cooler overall temperature.

Answers

Answer:

DNA: thymine, deoxyribose, large molecule, stay in the nucleus

RNA: single strand, uracil, leave the nucleus, small molecule

Explanation:

As for single strand, it's well known that DNA has two strands while RNA has one.

For the description that asks about thymine, you have to remember the nucleotide bases in DNA and RNA. Remember that DNA's bases are A, C, T, and G, while RNA has all the same bases except for T (which stands for thymine). In RNA, the thymine is replaced with uracil, usually abbreviated as U. That sorts out the descriptions that ask for thymine and uracil.

To figure out the one that asks for deoxyribose, remember that DNA has deoxyribose and RNA has ribose (hence why DNA is deoxyribonucleic acid while RNA is just ribonucleic acid.)

For the large molecule/small molecule ones and the questions that ask about the size of the molecule, remember that DNA is a way bigger molecule than RNA and that RNA is small enough to leave the nucleus, while DNA is much too valuable to the cell to be able to leave the nucleus.

Answer:

pulling further back on the string

Explanation:

I chose that because as for me answer 2 and 3 don't make sense but as for answer four I don't think that when you decrease the mass of the arrow this will increase the kinetic energy because for it to move faster I'll have to pull the string harder or to enlarge it ,so to increase the kinetic energy it is just determined by how I pull that string ."have I enlarged it or it is still loose."
