The main parts of a seed are Embryo, Endosperm, and Seed Coat
The three primary parts of a seed are the embryo, endosperm, and seed coat. The embryo is the young multicellular organism before it emerges from the seed. The endosperm is a source of stored food, consisting primarily of starches. The seed coat consists of one or more protective layers that encase the seed.
Wherein is the seed coat?The outer layer of the seed is called the seed coat, and it features to guard the plant embryo in the seed. It also encapsulates the endosperm, or food supply, for the embryo.

For lunch, Pat had a baked potato and Erin had a hamburger with no bun. They each consumed the same amount of biomass, but from different trophic levels. In comparison to the amount of land required to produce Pat’s potato, how much land was required to produce Erin’s hamburger?
a. about 10% as much land to produce the hamburger
b. about the same amount of land to produce the hamburger and the potato
c. about 10 times as much land to produce the hamburger
The land was required to produce Erin’s hamburger is about the same amount of land to produce the hamburger and the potato. Option B. This is further explained below.

Explanation:
Water in ocean currents can descend when it becomes colder and saltier than
the surrounding water. If water descends to the bottom of the ocean, then other
water must rise to the top. What causes water to rise to the top of the ocean?*
It is forced upward by underwater mountain ranges
It cools down and dissolves additional salt
It is brought upward by organisms that live in the ocean
It becomes less dense than the surrounding water
Answer: D it becomes less dense than the surrounding water
Explanation: when the water becomes colder and saltier it becomes more dense so the less dense water rises to the top.
Plants participate in both short- and long-distance signaling. Explain how nerve cells show these two functions, as well. (3 points)
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Nerve cells release hormones into the synapses between them (short distance). These hormones can also transverse the bloodstream (long distance).
Nerve cells release neurotransmitters into gap junctions between them (short distance). They also use electrochemical gradients that can travel the length of each cell quickly, along a network of cells (long distance).
Nerve cells use plasmodesmata to communicate between them individually (short distance). They also use ion-gated channels to create an electrochemical signal that can be propagated over long distances in their network (long distance).
Answer:
Nerve cells release chemical signals into synapses between them (short distance). They also transverse their lengths with an electrical signal that can result in signal travel along a series of cells (long distance).
Explanation:
Nerve cells release neurotransmitters in the synaptic cleft which are capable of affecting nearby cells such as other nerve cells and muscle cells. Neurotransmitter molecules include, among others, serotonin, acetylcholine, dopamine, norepinephrine and histamine. Moreover, the synaptic cleft is the space that separates a neuron cell and its target cell. On the other hand, neurons transmit signals through electrical impulses. Electrical impulses travel long distances in the body carried by axons of the nerves. Thus, nerve impulses connect the brain and spinal cord and they carry signals to different parts of the body.

What types of organisms have mitochondria
Answer:
sup ._.
Explanation:
The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.

given the Dna Strand: ATG-CAG-AGA how would i transcribe the corresponding RNA Strand ?
Answer:
The RNA strand that is transcribed from the DNA strand sequence ATG-CAG-AGA is UAC-GUC-UCU, according to the complementarity of nitrogenous bases.
Explanation:
In order for DNA to RNA transcription to occur, one must be aware that:
The transcription meets the criteria of base complementarity, where a purine binds to a pyrimidine. In RNA there is no thymine, so it is replaced by uracil.Given a given sequence of bases the RNA resulting from transcription will be governed by these rules:
DNA: ATG-CAG-AGA
RNA: UAC-GUC-UCU
Where:
Adenine is transcribed in Uracil. Thymine (DNA) is transcribed into Adenine. Cytosine is transcribed into Guanine. Guanine is transcribed into Cytosine.DESCRIBE THE FUNCTION OF A CELL MEMBRANE AND ITS RELATIONSHIP TO WHAT HAPPENS INSIDE A CELL

1. Fill in the reactants and products of the light-dependent and light-independent reactions of
photosynthesis.
Light-Dependent
Light-Independent
Reactions
Reactions
NADPH
ATP
THYLAKOID
ADP
STROMA
NADP
2. What is the NADPH responsible for?
3. Where do the "light" reactions (light-dependent) take place?
Answer:
A) Light dependent reactions
Reactants: light, H2O
Products: Oxygen gas
B) Light independent reactions
Reactants: C02
Products: Glucose
2. NADPH is an electron carrier which transfers electrons in the electron transport chain of photosynthesis
3. Light reactions occur in the THYLAKOID membrane.
Explanation:
As depicted in the image in this question, the photosynthetic process can be grouped into two stages viz; light dependent reactions and light independent reactions. The light dependent reactions, which take place in the THYLAKOID MEMBRANE of the Chloroplast, involves the synthesis of ATP (energy carrier) and NADPH (electron carrier) to be used in the next stage. The reactants of light dependent reactions are light energy from sun, and water (H2O) while the product is Oxygen (O2) gas.
In the light independent reactions, the ATP and NADPH are used to synthesize GLUCOSE as a product from Carbon dioxide (CO2) reactant.
2. The NADPH is is an electron carrier produced from the reduction of NADP+, which transfers or donates electrons to other molecules in the electron transport chain of photosynthesis. This is crucial in building of the proton gradient for ATP production.
3. The light reaction or light dependent reaction takes place in the THYLAKOID MEMBRANE of the Chloroplast.
The light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP. NADPH is a cofactor.
The light-dependent reactions use sunlight and water (H2O) to produce oxygen (O2), NADPH and ATP, whereas light-independent reactions use carbon dioxide (CO2) NADPH, and ATP to produce simple carbohydrates (e.g., glucose).Both light-dependent reactions and light-independent reactions occur in the chloroplast: light-dependent reactions occur in the thylakoid membrane of the chloroplast, whereas light-independent reactions occur in the stroma of the chloroplast.Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a cofactor that transports electrons (e-) and protons (H+) released by sunlight into new carbon-carbon bonds and thus serves to produce simple carbohydrates (i.e., sugars).In conclusion, the light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP to create carbohydrates.
