A new machine for harvesting corn will allow rows to be planted only fifteen inches apart, instead of the usual thirty inches. C

orn planted this closely will produce lower yields per plant. Nevertheless, the new machine will allow corn growers to double their profits per acre because ________.(A) with the closer spacing of the rows, the growing corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation(B) with the closer spacing of the rows, corn plants will be forced to grow taller because of increased competition for sunlight from neighboring corn plants(C) with the larger number of plants growing per acre, more fertilizer will be required(D) with the spacing between rows cut by half, the number of plants grown per acre will almost double(E) with the closer spacing of the rows, the acreage on which corn is planted will be utilized much more intensively than it was before, requiring more frequent fallow years in which corn fields are left unplanted

Answer:

A) With the closer spacing for the rows, the growing  corn plants will quickly form a dense canopy of leaves, which will, by shading the ground, minimize the need for costly weed control and irrigation.

Explanation:

If the space among plants is less, the shadow that they are going to produce is going to reduce the need of water, so they production will rise and the cost to maintain the crops will be less, so the producer can double the profits.

The Lincoln family has 3 children, 1 girl and 2 boys. What is the probability that their 4th child will be a boy?
goldfiish [28.3K]

Answer:

1/2

Explanation:

You have a 1/2 chance of having a boy and a 1/2 chance of having a girl.

Unless the question specifies whether or not there is a mutation present with the male parent, it is safe to assume there is a 50/50 shot of having a boy or girl.

G protein‑coupled receptors (GPCRs) and receptor tyrosine kinases (RTKs) are two basic receptor types by which cells transduce s
weqwewe [10]
<h2>GPCRs and RTKs</h2>

Explanation:

1) Phosphorylation of receptor can terminate signal or desensitize receptor: GPCRs because when signal persists a protein kinase receptor is activated,this further catalyse the phosphorylation of several serine residue at cytosolic phase of 7 transmembrane

Phosphorylated transmembrane recognized by arrestin protein blocks interaction between trimeric G protein and receptor thus blocks signal transduction

2) Autophosphorylation of receptor can initiate signal: RTKs because receptor dimerization activates intrinsic tyrosine kinase activity by which they phosphorylate its own tyrosine residue on cytosolic phase

3) Structure contains seven transmembrane helices: GPCRs because it consists of single polypeptide and spans the membrane 7 times hence called 7 transmembrane;it recognizes external signal and activates trimeric G protein

4) Ligand binding induces conformational change in receptor: RTKs because normally RTK exist in monomeric form in absence of any ligand molecule but when any ligand molecule binds receptor starts to dimerize

5) Receptor activation causes phosphorylation of its cytosolic subunits: RTKs because when receptor gets activates the intrinsic tyrosine kinase activity by which they phosphorylate its cytosolic subunits

6) An example is the insulin receptor: Insulin receptor is present on plasma membrane and belongs to RTK family and always exist in dimeric form

7) Transports some ligands through the membrane: Neither GPCR nor RTK;ligand gets transported through the membrane through ligand gated channel

8) An example is the epinephrine receptor: Epinephrine is an endocrine  hormone produced by adrenal glands in stress condition and prepare body for fight and flight;Epinephrine uses GPCR signalling pathway by four different types of membrane receptors in different tissues

9) Activate heterotrimeric G proteins directly: Transmembrane protein of GPCR recognizes the external signal and activates G protein,activated G protein binds with effector enzyme and activate it which further produce or destroy secondary messenger that carry message from cell surface to cell interior

If two parents have an autosomal dominant trait, what can you say about their children?
balu736 [363]

Answer:

If a child has an autosomal dominant trait, then at least one parent has the autosomal dominant trait. If both parents have an autosomal dominant trait, then all of their children will have that trait. If both parents have an autosomal recessive trait, then all of their children will have that trait.
