when do birds use their teeth????
Answer:
to eat worms
Explanation:
Answer:
Birds do not have teeth, however...Explanation:
[tex]--------------------------------------------[/tex]
According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

Pea plant has Round Seed dominant over Wrinkled Seed.
Round Seed allele is R
Wrinkled Seed allele is p
_____________________________________CONDITIONS:Hom.ozygous Dominant Alleles: RR (Round Seed)
Heter.ozygous Dominant Alleles: Rr (Round Seed)
Hom.ozygous Recessive Alleles: rr (Wrinkled Seed)
_____________________________________CROSS I:Whenever we cross Heter.ozygous Dominant(Rr) with Hom.ozygous recessive (rr), we get 50% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,
The P1 is Rr
The P2 is rr
When we cross them,
It has 4 offsprings,
Rr Round Seed
Rr Round Seed
rr Wrinkled Seed
rr Wrinkled Seed
Thus the answer is 50% round seed as there are 2 out of 4 heter.ozygous dominant round seed.
_____________________________________ CROSS II:Whenever we cross Hete.rozygous Dominant(Rr) with another Heter.ozygous Dominant (Rr), we get 75% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,
The P1 is Rr
The P2 is Rr
When we cross them,
It has 4 offsprings,
RR Round Seed
Rr Round Seed
Rr Wrinkled Seed
rr Wrinkled Seed
Thus the answer is 75% round seed as there are 3 out of 4 hom.ozygous and hete.rozygous dominant round seed.
_____________________________________CROSS 3:Whenever we cross Homo.zygous Dominant(RR) with Heter.ozygous Dominant (Rr), we get 100% ROUND SEEDS PHENOTIPICALLY(physical appearance), Because as you can see in the picture,
The P1 is RrR
The P2 is Rr
When we cross them,
It has 4 offsprings,
RR Round Seed
RR Round Seed
Rr Wrinkled Seed
Rr Wrinkled Seed
Thus the answer is 100% round seed as there are 4 out of 4 hetero.zygous and homo.zygous dom.inant round seed.

How the nervous and endocrine systems maintain homeostasis?
Answer:
Hope this helps :D
Explanation:
Homeostasis is the process of how you have a controlled body temperature.
The nervous system detects that your body temperature is falling (or rising) so the endocrine system send the chemical messengers (hormones) to bring the body temperature back to normal.
1. Are the following cell parts located in a plant cell, animal cell or both?
-Nucleus
-Cell Wall
-Mitochondria
-Cytoplasm
-Chloroplasts
-Vacuole
-Cell Membrane
Answer:
1. both
2. Plant cell
3. Plant cell
4. both
5. Plant cell
6. Both
7. Both
Explanation:
Plant cells have a cell wall and a cell membrane, unlike animal cells that only have a cell membrane.
Both have a cytoplasm, vacuole, mitochondria, and a nucleus.
Hope this is correct. Good luck with your studies.
Both plant cell and animal cell have a nucleus, mitochondria, cytoplasm, and cell membrane. Only a plant cell have cell wall, chloroplast and vacuole.
Difference between Plant cell and Animal Cell?Plant cells are the unit of plants. These cells are present in all green and non-green cells in a plant. However, an animal cell is the fundamental unit of an animal. Different types of animal cells make up an organism.
Plant cell contain an outermost covering called the cell wall. It protects them from shock and provides mechanical strength to the cell. It is absent in the animal cell.
Chloroplast is also present in the plant cells whereas it is absent in the animal cells. It is a double-membranous structure. A chloroplast is responsible for the process of photosynthesis as it contains chlorophyll pigment. A vacuole is also present in the plant cell and absent in an animal cell. The vacuole is responsible for the storage of reserved food materials in the form of complex sugars.

Hey there! please help I can't find the answer in my textbook for these notes :)
During the _________, ATP and NADPH molecules produced in the light-dependent reactions are used to produce high-energy sugars from carbon dioxide.
Thank you so much!
Answer: Overview of the Calvin cycle
In the Calvin cycle, carbon atoms from CO2start text, C, O, end text, start subscript, 2, end subscript are fixed (incorporated into organic molecules) and used to build three-carbon sugars. This process is fueled by, and dependent on, ATP and NADPH from the light reactions.
Which of the following problems are environmental indicators of acid deposition?
Decreased pH levels in lakes and rivers
Decreased concentration of aluminum in the soil
Changes in development of indicator organisms of an ecosystem
II only
III only
I and III
I and II
Answer:
I and III
Explanation:
Acid deposition will decrease pH levels in lakes and rivers since it contaminates them and lowers their pH, and organisms may be affected by the increased acidity in their immediate surroundings, but aluminum has nothing to do with pH levels at all.
Hope thish elped!
Option I and III shows the problems of environmental indicators of acid deposition.
The following information should be considered:
The acid deposition should reduce the level of pH in terms of lakes and rivers as it contaminates also the organisms should impact when the acidity should be increased for the surroundings. But the aluminum does not have any relationship with pH levels.Therefore we can conclude that options I and III are correct.

Studying which of the following would provide the best evidence that two organisms share a common ancestor?
A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions
Answer:
A
Explanation:
Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.
Amino acid sequence is a series of bases with different letters usually four(A T C G or U) this letter contains information of an individual when translated.
The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast
Blast generates alignments or similarities between a amino acid or protein sequence.For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.
Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.

Answer:
I dont see any diagram but in general, the organelles are the nucleus, ribosomes, ER, golgi apparatus, and vesicles
Explanation:
The nucleus contains the genetic code and creates the "orders" for the ribosomes
The ribosomes synthesize the proteins
The (rough) endoplasmic reticulum contain ribosomes
The golgi apparatus and vesicles transport and modify proteins
What is the difference between prokaryotic and eukaryotic cells?
The main difference that separates prokariotic organisms from eukaryotic organisms is the organisation of the genetic material. Prokaryotes have a single chromosome that isn't separated by a membrane and it's called nucleoid. Eukaryotes have multiple chromosomes that are inclosed in a nuclear envelope(nucleus).
The only organelles present in prokaryotic cells are the ribosomes(70S) which differ from the eukaryotic ribosomes(80S). Eukaryotic cells have membrane bound organelles like the mitochondrion or Golgi aparatus.

Describe how a solid rock in the lower level of the crust could become a molten rock.
PLS HELP I WILL MARK BRAINLIEST
Answer:
The higher the pressure on anything, the hotter it will get. The hotter a rock gets, the more possibility that it will have to melt.
So you're out the base of the crust, with any kilometers of crust above you, and that's a lot of pressure. Then take into account that you have thousands of degrees of heat coming from the mantle-core boundary, and directly from radioactive decay within the mantle, which only adds to the temperature.
The net result is like melting a stick of butter. It's very easy to do without a lot of energy -- since Earth is a massive ball of thermal energy, then well... it's easy to do.
