Answer and Explanation:
Tracheophyte plants, also known as vascular plants, are those that possess a supportive tissue that can also conduct fluids -The Xileme- and another tissue that conducts nutritious elements produced by photosynthesis -The Phloem-. These plants have a root (basically underground), a stem (aerial), and leaves. All of them together form the corm. And the corm counts with these vascular tissues to which we referred before.
There are different types of Tracheophyte plants, some of them produce seeds to reproduce and disperse -Spermatophyta- and some others reproduce and disperse by spores -Pteridophyta-. This last seedless group corresponds to ferns and other similar plants.
Pteridophytes characterizes for having a sporophyte that has stems with leaves and a root. It also has primitive xylem composed by tracheids and phloem, both of them formed by vascular bundles located in a central cylinder.
Spores are its dispersion units and are responsible for colonizing new areas. They also constitute the resistance units under extremely unfavorable conditions.
Their life cycle is composed of the asexual phase (sporophytic phase) and the sexual phase (gametophytic).
The sporophyte, the dominant asexual generation, it is a perennial and diploid structure. Its aerial part might disappear during unfavorable seasons, but it reappears during spring or summer. The sporophyte is in charge of asexual reproductionThe gametophyte, instead, is and haploid structure, ephemeral and must be in the water for its survival, and for sexual reproduction to be successful. In the presence of water, masculine gametophyte -antherozoids- are released and they swim to the archegonium to meet the ovocell. Antherozoids can swim because they have flagella. After fertilization, a new sporophyte is produced."Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the ____________"
Answer:

Which is an example of foraging as a benefit of social behavior?
A blue jay eats birdseed from a bird feeder.
Three lions hunt and capture a zebra.
Worker bees build a nest and the queen bee lays eggs.
A male chimpanzee mates with several different females.
Answer:
The correct answer is - Three lions hunt and capture a zebra.
Explanation:
Social behavior is an interaction between two or more organisms of the same species normally, in order to benefit one other. Social behaviorism most of the time is beneficial to the individuals and to the species.
Foraging is a behavior that includes all the processes or methods that are included in getting nutrients and food for the individual organism. Three lions together hunt and capture a zebra is an example of foraging as a benefit of social behavior.
Thus, the correct answer is - Three lions hunt and capture a zebra.

In your own words, describe the purpose and process of translation. The purpose of translation is… The process of translation is...
Answer:
the purpose of the translation is to make proteins. proteins are responsible for making bones, muscles, cartilage, skin and blood. proteins are synthesized from the information in a mRNA.
Process of translation
it happens in 3 phases
initiation: the small ribosomal subunits binds to the start of the of the mRNA sequence. then a tRNA molecule carrying the amino acid methoionine binds to start codon of the mRNA sequence. after that large ribosomal subunit binds to form the complete intiation complex.elongation: the ribosome continues to translate each codon in turn each corresponding amino acid is added to the growing chain and linked via bond called peptide bond. elongation continues untill all the codons are read.termination: it occurs when the ribosome reaches a stop codon. since there is no tRNA molecules that can recognise these codons the ribosome recognises that translation is complete.after these 3 phases a new protein is realeasd

list the order in which the body will consume carbohydrates, lipids, and proteins for energy, and explain why. Based on this informatoin, include what diet and excercise plan would be the best for someone trying to lose weight
Answer:
carbohydrates, lipids, and proteins
Explanation:
The above sequence is the correct other.CHO foods are easier to process breakdown by the body through glycolysis, Kreb's cyle and oxidative phosphorylation of ETC than other sources especially lipds. Hence, it is faster for the body to dispose the energy contained for biochemical activities. Specifically the oxygen required for metabolism and oxidation of CHO is very low compare to the amount needed for the same function in lipids. Therefore energy supply for CHO metabolism is the lowest and easier to extract the energy contained- as in glucose and starch.
Lipids -fats and oils have large sources of energy.But the longer process for metabolism(as stated above) and extracting the stored energy is longer.This is because of the longer hydrocarbon chains which must be metabolize by longer oxidative phosphorylation process, for required ATPs to be obtained.However,the energy storage is high due to more Protons for electrochemical gradients.
Proteins take longer period to undergo metabolisms in the body. This reflects in the complexity of the macro molecules they are made of.Therefore release energy at a slower rate,but long lasting compare to CHO. This is because the sequence of oxidative phosphorylation takes longer period to generate ATPs.
Protein is the ideal diet to embrace if to loose weight.
This is because,proteins usually suppresses the activities of hunger hormones,Thus the individual eat less,but increases the secretion of Leptin. This is a satiety hormone,an hormone that suppressed appetite,Hence, the individual eat less, consume lower amount of calories and therefore loose weights.
calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.
Answer:
144
Explanation:
Population growth rate refers to the measure of how a population (N) changes over a particular time (t). Hence, it is termed as (dN/dt) where d represents the change.
The logistic population growth rate equation is given as:
dN/dT = rmaxN (K-N/K)
Where; dN/dt = population growth rate
K = carrying capacity of
population
rmax = maximum per capital
growth rate
N = population number
dN/dt = 0.3 × 1200 (2000-1200/2000)
dN/dt = 360 (800/2000)
dN/dt = 360 (0.4)
dN/dt = 144
Hence, the growth rate of the population (dN/dt) is 144
Select one organism that lives in the Ecosystem and describe three adaptations the organism possesses. Explain why the adaptations are important to the organism’s survival?
Explanation:
Hey, there!
The eco-system consists of various type of organisms in tge ecosystem. The all type of organism as producer, decomposer, consumers live in ecosystem.
Three adaptations of organism are:
By losing and gaining of organs: Some of the animals lose their organs to survive in some places like yak have more hair to survive in cold places.By changing the colour of body: Some animals such as grasshopper changes their colour to survive in places.By modification of organs: some animals modify their organs to survive such as legs and beak of ducks are modified to survive in swim and search foods.The importance of adaptation are:
It helps organism to live a longer life.The adaptation helps to make an organism fittest to any environment. The adaptation helps an organism to search foods and live their life.Hope it helps...

Could the loss of 4% of the cerebral cortex cause the behavior changes noted in Phineas Gage?
Answer:
Yes
Explanation:
The frontal lobe is the part of the brain that controls personality, decision-making and reasoning. It is a part of the cerebral cortex and the largest in composition.
Phineas Gage was involved in an accident in which a metal rod destroyed parts of his brain. This incident however brought about a drastic change in his behavior.
This incident helped to establish the relationship between the frontal lobe and behavioral patterns.
In a salt marsh in Georgia, the quantity of solar radiation reaching the ground during the summer is 7,000,000cal/m2/day. The gross productivity of the producers in the salt marsh (mostly microscopic algae) is 0.0040 g/cm2/day. The average rate of respiration (the respiration requirement) is 35% of the gross primary productivity. Ecologists have found that 1 gram of salt marsh producers (the algae) is equivalent to 2,920 calories. Calculate the net primary productivity of the system, in g/m2/day. (remember, 1 m2 = 10,000 cm2)
Answer:
NPP=26 g/m²/day
Explanation:
Important data:
1 m² = 10,000 cm²NPP = GPP - Respiration NPP= Net primary productivity of a systemGPP= Gross productivity of the producersAvailable Data:
GPP=0.0040 g/cm²/dayRespiration rate= 35% of the gross primary productivityWe need to calculate the NPP, which equals GPP - Respiration rate.
The respiration rate is 35% of the GPP. This is:
100% GPP--------------- 0.004 g/cm²/day
35% GPP ----------------X = (35 x 0.004)/100 = 0.0014 g/cm²/day
Now that we know the values of GPP and respiration rate, we can calculate the NPP.
NPP = GPP - Respiration
NPP = 0.004 g/cm²/day - 0.0014 g/cm²/day
NPP = 0.0026 g/cm²/day
Now we also know the NPP, but this value is calculated in g/cm²/day, and we need to calculate it in g/m²/day, so if 1 m² = 10,000 cm², then:
1 cm²---------------- 0.0026 g/cm²/day
10,000cm²----------X = (10,000 x 0.0026)/1 = 26 g/m²/day
