how do ferns reproduce?
Ferns produce male and female cones.
Ferns produce spores under its leaves.
Ferns produce egg and sperms cells in the leaves.
Ferns produce flowers that contain egg and sperm cells.
Answer:
The answer is C.
Explanation:
Most ferns reproduce differently, and that involves meiosis and fertilization. When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. The spores are released into the wind.
Answer: The correct answer on Ody2020 is: Ferns produce spores under its leaves.
Explanation: Got it right on the assignment.
You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

Explain how the method of mark and recapture works to determine population size.
Answer:
A number of members of a population are capture, tagged, and released. At a later time, the sampler returns and captures a set number of members of the population and determines the ratio of tagged to untagged individuals. The ratio of tagged to caught individuals is then approximately equal to the ratio of originally tagged individuals to the total population.

A study was created to test the effects of jazz on people’s sleep patterns. The hypothesis of the experiment was that if people listened to jazz music as they fall asleep, they will sleep for longer periods of time. For the experiment, 2 groups of people were created. One group was placed in a quiet room where they went to sleep and they were timed on how long they slept. The other group was placed in a room where jazz music played softly as they began to sleep and played throughout the night. As each group awoke, their sleep times were monitored.
Dependent Variable: ______________________ Control Group: ____________________________
Independent Variable: _____________________ Experimental Group: ________
Answer:
Dependent variable - sleep times
Independent variable - jazz music/silence
Control group - Group 1. The group that was kept in a silent room
Experimental group - Group 2. The group placed in a room with jazz music.
Explanation:
The dependent variable is the actual variable to be measured during an experiment. The value of the dependent variable is dependent on the independent variable supplied. In this case, the dependent variable is the duration of sleep of the different groups.
The independent variable is supplied by the experimenter and is often manipulated to see the effects it will produce on the dependent variable. In this case, the jazz music and the silence in the rooms respectively represent the independent variable.
The control group receives no treatment variable and represents the group that is often used as the benchmark to measure the effects of treatment variables on experimental subjects. In this case, the control group is the group that was placed in a room without jazz music.
The experimental group is the group that receives the treatment variable and in this case, the group that slept in the room filled with jazz music.
Dependent Variable: The dependent variable in this experiment is the sleep duration or the length of time each participant slept.
Control Group: The control group in this experiment is the group of people placed in a quiet room where they went to sleep without any jazz music playing. This group serves as a baseline for comparison to evaluate the effects of jazz music on sleep duration.
Independent Variable: The independent variable in this experiment is the presence or absence of jazz music while falling asleep and throughout the night.
Experimental Group: The experimental group in this experiment is the group of people placed in a room where jazz music played softly as they began to sleep and continued to play throughout the night. This group is exposed to the independent variable (jazz music) to test its effect on sleep duration.
The purpose of this study is to determine if the independent variable (jazz music) has an impact on the dependent variable (sleep duration) by comparing the control group's sleep duration to that of the experimental group.

justify how birds belonging to different species might all share a common ancestor.
Answer:
When two different species having similar ancestors evolve to become different is called divergent evolution.
Birds belonging to different species might all share a common ancestor are also based on divergent evolution. Animals undergo divergent evolution for several reasons such as enviornmental changes and existance or absence of predators.
Some animals or birds adapt according to enviornmental changes for their survival and presence of predators affect the evolution of animals or birds to protect themselves from predators.
For example: Galapogas finches undergo divergent evolution in which they have same ancestors but radiates into different species such as medium ground finches, woodpecker finch, and mangrove finch.

The diffusion of a substance into or out of a cell requires
Answer:
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.
Explanation:
The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.
What is diffusion?Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.
There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.
Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when
the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to
move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.
Donna records her data.
The missing part of the question is as follows:

Dependent Variable:
Time it takes the pendulum to swing or move
Independent Variable:
the position of the weight
Constants:
same weight and the same number of swings
Control Group:
pendulum at the lowest position
Experimental Group:
different height of pendulums
Explanation:
A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.
The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.
Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.
