Which of these is an autotroph?
A.
mackerel
B.
squid
C.
mollusks
D.
fungi
E.
phytoplankton
Answer:
E.
phytoplankton
Explanation:
The defenition of Autotroph is: "an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide." (Oxford Dictionaries)
As Britannica says, "[...]Like land vegetation, phytoplankton uses carbon dioxide, releases oxygen, and converts minerals to a form animals can use."
Then Wikipedia (I know, not the best source, but it works) says, "Phytoplankton (/ˌfaɪtoʊˈplæŋktən/) are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems."
So, Phytoplankton is an autotroph.
Cattle get most of their energy from
minerals.
carbohydrates.
vitamins.
fats and oils.
Answer:
fats and oils.
Explanation:
You may wonder how the heck a large animal like a cow gets any energy from grass. The answer lies in these microbes. As they digest the cellulose by way of fermentation, their metabolic pathways produce chemicals called volatile fatty acids (VFAs) or fat sources (oilseeds, animal, and vegetable oils).

why the concentration of nitrate ion in the soil had decreased after the farmer grew maize plants in the field?
Answer:
because the maize plant will take in the nitrate and use it to make proteins for growth.
The concentration of nitrate ion (nitrogen) in the soil decreases after the farmer plants maize plants in the field because the maize plants have taken up these ions.
Does maize require nitrogen?To develop and produce, maize plants need a lot of nitrogen. 160 kg/ha of nitrogen are removed on average by maize crops.
What purpose does nitrogen serve in maize?Due to its function in photosynthesis and other biological activities like mineral and water absorption, vacuole storage, and xylem movement, nitrogen is a crucial nutrient for maize and a major regulator of grain output.
What type of fertilizer is ideal for maize?The growth, yield, and quality of maize crops are most strongly influenced by nitrogen.
Fertilizer with nitrogen is necessary for healthy leaf growth.
What happens if the leaves of maize are small?Less photosynthesis, which is necessary to store starch in grains, occurs as a result of smaller leaves.

Why do urban areas experience warmer temperatures compared to surrounding rural areas?
A. Urban areas have more surfaces that absorb and hold heat

this is because building sidewalk and parking lots blocks heat coming from the ground from rising into the cold night sky because the heat is trapped on lower levels the temperature is warmer
How do mammals compare with birds and reptiles in terms of temperature regulation and structure of the heart?
Answer:
the biggest difference is that mammals are endothermic and internally regulate their body temperature, but reptiles are ectothermic because they rely on the environment to do it for them.
Explanation:
Ectothermic: An ectothermic animal, also commonly known as a "cold-blooded" animal, is one who cannot regulate its own body temperature, so its body temperature fluctuates according to its surroundings. The term ectotherm comes from the Greek ektos, meaning outside, and thermos, which means heat
Endothermic: An endothermic process is any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions takes in energy and the temperature of the surroundings decreases.

Don't copy from the internet, If you do, Summarize it into an answer no longer than 2-3 sentences and make it your own words
BIG BRAIN ANSWER:
Before Darwin, a naturalist named Jean-Babtiste Lamarck believed that the environment altered the shape of individuals and that these acquired changes were then inherited. Meanwhile, Charles Darwin was a naturalist on a ship called the HMS Beagle, and he discovered that the beak shape varies among finch species in the Galapagos Islands. He found that the beak of an ancestral species of finch had somehow been transported to these islands, and adapted over time to acquire different food sources that were available, causing variation, and that nature just selected for the most suitable beak shape and against less useful ones.

Answer:
III3 will be "pp" lower case p
II2 will be Pp
Explanation:
As we know the trait is caused by dominant alleles. III3 is not affected so she will have two recessice alleles so 2 lower case p.
III2 is affected so the person will have one dominant allele P and one recessive. The dominant is from the father and the recessive is from the mother.
Hope that helps
Answer:
1. pp 2. Pp
Explanation:
1. Since it says the genetic disorder is caused by a dominant allele, that means that the ones affected (colored in) would have one "P" allele. Those not affected (not colored in) would display the genotype "pp." That would mean that generation III-3's genotype would be "pp."
2. The genotype of III-2 is "Pp." The dad was not affected (meaning he has 2 recessive alleles, pp) and the mom was affected (meaning she has at least 1 dominant allele, p; her genotype would either be PP or Pp). Because of this, III-2 would have to get one allele from the dad and one allele from the mom, therefore... their genotype would be: Pp.

Answer:
I think row 2.
Explanation:
i thinks it's the best answer here.
The process involved in human reproduction is: meiosis occurs in both A and B to produce sperm and egg respectively which after fertilization forms zygote which undergo into differentiation which causes this embryo to transform into human child.
What is reproduction?"Reproduction is the biological process by which new individual organisms or offspring are produced from their parents."What is meiosis?It is a type of cell division which occurs in s ex cells.The number of chromosomes reduced to half and produces four daughter cells.What do you mean by fertilization?"The fusion of male and female gamete is called fertilization."The fusion leads to the formation of zygote.What do you mean by differentiation?"It is a process in which a stem cell alters from one type to a more specialized type."Hence, row (2) represents processes involved in human reproduction.
