In fruit Flies a white eyed female is crossed with a red eyed male. What are the changes the offspring will be a white eyed male?
Answer:
the chances of the offspring having white eyes is 50%
Explanation:
i used a punnet square to calculate the output:)
Answer:
25%
Explanation:
There's a 50% chance of the offspring being male & 50% chance female. The genotypes must be co-dominant otherwise their question doesn't give enough information to get an anwser. Also a 50/50 chance of red/white, so added together a 25% chance.

2. Epithelial tissue.
3. Nervous tissue.
4. Connective tissue.
5. Epithelial tissue.
6. Muscle tissue.
7. Connective tissue.
Explanation:
A tissue can be defined as a group of cells that are structurally similar and in close proximity. Tissues are generally responsible for performing specific functions in living organisms such as humans, animals and plants. Therefore, tissues in living organisms function together as a unit.
There are four main types of tissues and these includes;
I. Connective tissue.
II. Epithelial tissue.
III. Muscle tissue.
IV. Nervous tissue.
In this scenario, the various types of tissues are matched with their functions as follows;
1. Muscle tissue: propels food through the digestive tract. It is mainly performed by peristalsis.
2. Epithelial tissue: lines internal and external body surfaces. It also referred to as epithelium and it comprises of sheets of cells.
3. Nervous tissue: conducts electrical impulses. A neural circuit can be defined as a group of neurons in the body of a living organism which are interconnected by synapses to perform specific functions when they're activated.
4. Connective tissue: transports oxygen to the body tissues predominantly through the Erythrocytes (red blood cells).
5. Epithelial tissue: functions in secretion and absorption.
6. Muscle tissue: pumps blood.
7. Connective tissue: stores fats and minerals.

Some tRNAs contain inosine, which can base pair with A, C, and U. Why might this be advantageous with regards to the genetic code
The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.
What is tRNA?A form of RNA molecule called transfer ribonucleic acid (tRNA) aids in the translation of a messenger RNA (mRNA) sequence into a protein.
Translation, which creates a protein from an mRNA molecule, uses tRNAs at particular locations on the ribosome. A protein's amino acid composition is determined by codons, which are three-nucleotide mRNA sequences.
Every codon corresponds to a distinct amino acid, and every codon is accepted by a particular tRNA. The three hairpin loops that make up the tRNA molecule's characteristic folded structure give it the appearance of a three-leafed clover.
Therefore, The tRNAs contain I sound that base pair A C U advantageous to the species rabbit.

_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
Complete question:
The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K
TrueFalseAnswer:
TRUE
Explanation:
The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.
Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.
Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.
K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.
Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

Answer: The amount of water in the stream and the gradient.
However if you had two streams both with the same amount of water in them but with one stream flowing down a steeper slope (gradient) than the other, then the steep one has more ability to erode.
Explanation:
Water balance is intimately connected to the maintenance of blood pressure in the circulatory system. Changes in total blood volume directly relate to changes in blood pressure: higher blood volume leads to higher blood pressure, while lower blood volume leads to lower blood pressure. Considering this, what effect could hyponatremia have on blood pressure
Answer and explanation:
Water volume and blood pressure are directly linked with one another, and the regulation of these parameters is fundamental to maintain homeostasis and make life possible.
Hyponatremia is a condition in which sodium levels in blood are below normal (normal being between 135-145 mEq/l). When sodium concentration decreases to this pathological point, the blood becomes "diluted" because of the lack of this vastly important ion. To compensate the dilusion produced in blood, water will start moving from this tissue to enter the cells -thanks to a phenomenom called 'osmosis'-, swelling the cells and developing into a life-threatening condition. As a result of the influx of water, the volume levels in the extracellular compartment (with includes blood) will decrease, leading to a blood pressure decrease as well.

Answer:
disturbance plays in competition.
Explanation:
Fire-dependent pitch pine trees (Pinus rigida) is replaced by black locust (Robinia pseudoacacia) because of disturbance that occurs in the environment naturally. When disturbances occur naturally, they provide conditions that favor the success of different species over the native organisms. The native organisms are vanished from that ecosystem due to changing of environmental conditions and other organisms settle there which can survive in that environment.

How in the world r wolfs endangered?!!!! They hunt in packs so humans would at least need a semi-automatic riffle or something like that and before he/she kills all the wolfs more than likely they will be died so will give u all my points
Answer:
Humans are a big reason for this issue. Things such as pollution, hunting, construction, and animal testing all effect the wolves population. Their food is hunted by humans so its harder for them to hunt, humans tear down trees and take over ground so theres less places to live, they might eat things like plastic because people litter, and things like dangerous weather can harm these animals.
Is it a good idea for humans colonize mars pls real answers :)
Answer:
I believe yes and no at the same time
Explanation:
If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?
Answer:
Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors
But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains
In conclusion, no it would not be a good idea.
Case 12-2 Mother Goose Computing, Inc. provides computational biology consulting services. They are currently updating several of their systems. For the genomics division, Mother Goose is planning to replace the old system by the new one all at once. This is called a ____ conversion.
Answer:
Direct.
Explanation:
An information system can be defined as a set of components or computer systems, which is used to collect, store, and process data, as well as dissemination of information, knowledge, and distribution of digital products.
Generally, it is an integral part of human life because individuals, organizations, and institutions rely on information systems in order to perform their duties, functions or tasks and to manage their operations effectively. For example, all organizations make use of information systems for supply chain management, process financial accounts, manage their workforce, and as a marketing channels to reach their customers or potential customers.
Additionally, an information system comprises of five (5) main components;
1. Hardware.
2. Software.
3. Database.
4. Human resources.
5. Telecommunications.
Hence, an information system interacts with the overall system by receiving data in its raw forms and information in a usable format.
In this scenario, Mother Goose Computing, Inc. are currently updating several of their systems. For the genomics division, it's planning to replace the old system by the new one all at once. Thus, this is called a direct conversion.
Direct conversion can be defined as a process which typically involves the establishment and implementation of a new system followed by an immediate discontinuation of the old system all at once. Thus, on a particular date and time, the old system would be discontinued while the new system is immediately adopted for use in the particular organization.
