Energy flow is the amount of energy that moves through a food chain in a given ecosystem

Answer: Chemical reactions can either absorb thermal energy or release thermal energy.

Answer:

The medium of the wave is the Rope.

Explanation:

This is because it is transverse wave and transverse wave need a medium to transfer energy and this is because in transverse wave,particles of the medium move in a direction that is perpendicular to the direction of the transverse wave. From the question, when you move you hand up and down, you make a wave and the direction of the wave is also up and down which is perpendicular to the direction of the wave.

Answer The DNA in a cell is all the same

Explanation:

Answer: The correct option is A

any heritable trait

Explanation:

This is because phylogenetic tree is a diagram that show or indicate the evolutionary relationships between several organisms from a descent or that have common anscetors which is based on the differences or similarities of there phenotypic traits or physically expressed inheritable traits.

Answer:

Earth's rotation and the gravitational pull of the sun and moon create tides on our planet. Because the sun is so much larger than the moon (27 million times more masssive), it has a much bigger graviational pull on Earth.

Answer:

Newton's First Law of Motion

Explanation:

A body at rest persists in its state of rest, and the body in motion remains in uniform motion along a straight line unless acted upon by a net external force.

Answer: True

Explanation:

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

no

Explanation:

Answer:

deletion or insertion of nucleotide from or in any coding sequence of the DNA

Explanation:

The mutation would be most harmful to the cells if it resulted in the deletion or insertion of nucleotide from or in any coding sequence of the DNA.

Deletion or insertion of a nucleotide from/into the coding sequence of DNA results in a frameshift mutation away from the original protein. Deletion/insertion of a nucleotide from/to the coding sequence of a DNA can cause a totally different protein to be synthesized from such DNA or, worse still, results in a nonfunctional protein. Both results could be grossly harmful to the cells.  

Answer:

Transcription into mRNA strand will produce: ACU CAG CUG ACC GAC UGG CAU CUG

Translation into amino acid sequence will yield: Threonine- Glutamine- Leucine- Threonine- Aspartic acid- Tryptophan- Histidine- Leucine

Explanation:

- Transcription is the process by which DNA template is used to synthesize a mRNA molecule in the nucleus (eukaryotes). The transcription, which is carried out by an enzyme called RNA polymerase, follows the complementary base pairing rule i.e. A-T, G-C. Note that Uracil replaces Thymine in the RNA molecule.

Based on this question in which a DNA strand was given as follows: TGA GTC GAC TGG CTG ACC GTA GAC

The mRNA strand that will result from transcribing this DNA will be: ACU CAG CUG ACC GAC UGG CAU CUG

- Translation is the process by which mRNA strand is used to synthesize amino acid sequence (protein) in the ribosomes. In the mRNA sequence, nucleotides are read in a group of three called CODONS. Each codon specifies an amino acid. Based on the mRNA sequence as follows: ACU CAG CUG ACC GAC UGG CAU CUG, the amino acid sequence that will result after using the genetic code will be: Threonine (Thr)- Glutamine (Gln)- Leucine (Leu)- Threonine (Thr)- Aspartic acid (Asp)- Tryptophan (Try)- Histidine (His)- Leucine (Leu).

Answer:

D. Reforestation

Explanation:

Reforestation is a natural or intentional way of restoring existing forests and woodlands by restocking it after they have been depleted through deforestation. Forest industry makes use of forest product for production this includes log, paper and pulp production. Ability to restock after felling of this tree for product making helps continuation.

Reforestation helps to rectify the effects of deforestation and this helps to improve our health in turn by absorbing pollution and dust from the air.

Answer:

D. Focus on steady harvesting of abundant resources

Answer and Explanation:

Rock is defined as the collection of one or more minerals. Granite, sedimentary rock, igneous rock, metamorphic rock and limestone are the types of rock. Granite is the most common type of rock. Granite is made up of four minerals such as hornblende, feldspar, quartz and mica. Granite breaks down to form sedimentary rocks. Igneous rock begins as magma. The lava and magma harden to form igneous rock. Metamorphic rocks are made from pressure.  Rocks are made of one or more minerals, which are cooled and melted together, cemented together, or heated and squeezed together. The mineral occurs naturally and is made of crystals. The earth’s crust is made of rocks. Most rocks are covered by soil. Soil contains the small pieces of rocks.  The two rocks have similar composition but different texture. Rocks are formed in different ways. The rocks can be changed from one form to another.

Answer:

Crust- ranged from 6km to70km thick .

mantle- convection here leads to earthquakes.

Core -has a liquid and soild layer

Moho barrier- separates the crust and mantle.

Explanation:

HOPE this helps

The layers of the earth are differentiated based on their composition and occurrence. The crust is 6 -70 km thick, and the mantle is where the convection occurs. Thus, the matches are 1. c, 2. d, 3. b, and 4. a.

Earth has many different layers based on their arrangements and occurrences. The crust is the first layer of the earth where humans and other organisms live and ranges from 6 -70 km thick. It is followed by the Moho barrier.

The Moho barrier is the layer that separates the crust from the mantle and is followed by the mantle layer where the convection in the tectonic plates leads to earthquakes.

The deepest and the innermost layer is the core where the solid and liquid hot gases are found at very high temperatures. It is very hot and composed of iron and nickel.

Therefore, the matches are 1. c, 2. d, 3. b, and 4. a.

Answer:

Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.

Answer:

Ethanol and carbon dioxide

Explanation:

Answer:

The correct answer is - they may not be able to survive at such a temperature.

Explanation:

A Cold front is a weather change when a cooler air mass moves into warmer air that leads to a sudden drop in temperature following by the cyclone, heavy rainfall and hail.

These sudden changes and heavy rain with storms and cyclones can limit the population growth of newborn offspring as they may not able to survive in such a sudden temperature drop.

Answer:

Mouth -Esophagus-- Stomach -Duodenum -Jejunum -Brush border disaccharidases--Glucose transporters--Active transport--Blood-Glycolysis-Pyruvate--Citric acid cycle - Carbon dioxide and water  : )

Explanation:

The journey of a glucose molecule from the mouth and ultimately to the muscle cells for energy in the correct order is:

Mouth  > Esophagus  > Stomach > Duodenum  > Jejunum  > Brush Border Disaccharidases  > Blood  > Glucose Transporters > Glycolysis  > Pyruvate  > Citric Acid Cycle  > CO2 and Water  > Active Transport  > Electron Transport System.

The drink rich with disaccharides starts its journey from the mouth cavity and moves through the esophagus to the stomach. The disaccharide digestion takes place when it reaches the jejunum through the duodenum of the small intestine by enzyme maltase that also presents in Brush Border Disaccharidases to glucose.

Glucose moves o blood and through a glucose transporter for cellular respiration that starts with glycolysis that converts glucose to pyruvate and enters in TCA cycle and releases CO2 and water as byproducts that ultimately moves to the ETS system to provide energy to the muscles.

Thus, the correct answer is - given above in the correct order.

Explanation:

Income and fertilizers have nothing to do with it, so those are not it. Then there are shelter and windbreakers. It kind of acts as a shelter, but mainly it protects crops and homes by acting as a windbreaker. If it was shelter, that would mean that the crops would mainly be planted under the trees to reduce damage from storms and typhoons. Therefore, it is D) Windbreakers.
